I am writing to express my significant disappointment and frustration with the performance of Cursor AI version 0.49.6. Despite having upgraded to the Pro version, the application has been consistently hanging and crashing every few minutes, making it completely unusable for my work. Here are the specific details of my setup: - Version: 0.49.6 (user setup) - VSCode Version: 1.96.2 - Commit: 0781e811de386a0c5bcb07ceb259df8ff8246a50 - Date: 2025-04-25T04:49:20.797Z - Electron: 34.3.4 - Chromium: 132.0.6834.210 - Node.js: 20.18.3 - V8: 13.2.152.41-electron.0 - OS: Windows\_NT x64 10.0.19045 ---

Immediate crashes for me as well on 0.49.6 - windows 11 ---

Try downgrading then upgrading to the latest version of cursor - this seems to have sorted the issue for me. If the issue persists try: - Start by disabling extensions one by one to identify problematic ones - You can check Developer Tools (Ctrl+Shift+P \> “Developer: Toggle Developer Tools”) for any memory-related errors - Clear app data as a last resort (This will delete all your app data, including extensions, themes, snippets and other installation-related data. Please export your profile first to avoid losing this data.) ---

I’ve traced the issue down to a conflict with one of my extensions. I’ll confirm the exact culprit tomorrow, but given the recent significant updates to chat and chat history features, I’m suspecting it’s likely the SpecStory extension causing this. ---

Hey Jac1092, if you can provide any details re: the crashes and what version of SpecStory you’re on, would appreciate it: [Is this the cause of Cursor suddenly closing without warning? · Issue #54 · specstoryai/getspecstory · GitHub](https://github.com/specstoryai/getspecstory/issues/54) Also, if you turn off auto-save w/ SpecStory installed on activation, it would be interesting to know if you experience instant crashes. We rewrote the entire extractor in SpecStory v0.10.1+ to account for the chat/chat history data updates in Cursor v0.49.X. Depending on how large your state.vscdb is and how much chat history needs to migrate to their v3 format tends to be correlated with the behavor some have experienced. ---

Hey buddy, I’ll get back to you tomorrow on the above but wanted to quickly reply and say thanks for SpecStory.. I find it invaluable for my day to day. I have extended its feature set a bit, notably with a daily (end of coding ) session feature where it uses the chat history and the cursor rules to see what rules should be added or updated based on the pitfalls during the session. Oddly enough I use cline to work it way through it since it’s pretty solid at acting robotically through things. (One call per rules file) I’ve been working on another feature that takes the daily SpecStory log + TaskMaster (task.json) and build a daily dev log akin to a scrum note and have it a part of the repo for myself and the dev team. Anyway, great product and I happy to be able to tell you directly that I appreciate it. John ---

I’m also experiencing frequent crashes on 0.49.6. I’m using Windows 10. Version: 0.49.6 (user setup) VSCode Version: 1.96.2 Commit: 0781e811de386a0c5bcb07ceb259df8ff8246a50 Date: 2025-04-25T04:49:20.797Z Electron: 34.3.4 Chromium: 132.0.6834.210 Node.js: 20.18.3 V8: 13.2.152.41-electron.0 OS: Windows\_NT x64 10.0.19045 The crashes just started happening, without any changes on my part. The app could have updated automatically from 0.49.5 (maybe)? I also have the SpecStory extension installed but not sure if that’s the issue. ---

Same here. Any solution anyone. Tough first week at it. Glad it isnt just me though so i know i didnt do it.

@jac1092 @dcompt, others: we just got to the root of the bug affecting some and were able to reproduce it and fix it for the SpecStory extension. **The newest release 0.11.3 as of this morning fixes it.** If you’d like please download and let me know if it resolves for you. The release takes a bit to populate to the Extension Marketplace in Cursor, in the meantime, you can download and install the VSIX from either: [Open VSX Registry](https://open-vsx.org/extension/SpecStory/specstory-vscode) or [Install the extension - SpecStory](https://docs.specstory.com/introduction#install-from-vsix) Steps to reproduce on `0.11.2` and before running Cursor `0.49.6` (which are likely somewhat dependent on machine resources but I was able to repro consistently with a M4 Pro and 48gb of ram which is quite beefy): - Have `auto-save` in SpecStory turned on in settings - Have a state.vscdb in globalStorage that exceeds 500MB (mine for reference is ~800MB+) - Have a mix of v2 and v3 composerData in said state.vscdb - Open 8+ Cursor windows for projects simultaneously. We did this by turning off `auto-save` opening up the windows, turning on `auto-save` and force quitting Cursor so it would remember the workspace window sate. - On startup when SpecStory activates and Cursor runs its initial processes after ~30 seconds it will crash The fix was ultimately quite simple in terms of delaying an initial autosave attempt on startup and letting the polling process work normally. Finally, even in `0.11.2` and before if you opened 1 or 2 Cursor windows normally with `auto-save` on it **would not crash** which made it difficult to trace the root cause. ---
