everything working but ı have no clue why happening

deanrie · January 5, 2026, 2:05pm

I see you’re getting a specific error: serialize binary: invalid int 32: 4294967295. This is a known issue related to PowerShell on Windows.

Please try this:

Switch your terminal from PowerShell:
- Settings CTRL+, then search for terminal.integrated.defaultProfile.windows
- Pick Git Bash or Command Prompt
- Restart Cursor
Share your Cursor version:
- Help > About > Copy, then send the result
Share the Network Diagnostics results:
- Cursor Settings > Network > Run Diagnostics
- Send a screenshot of the results

This error usually happens when PowerShell returns specific exit codes. Switching the terminal should fix it. Let me know how it goes.

deanrie · January 5, 2026, 2:39pm

I see the issue. You tried to run terminal.integrated.defaultProfile.windows as a command in the terminal. It’s not a command, it’s a setting in the UI.

Correct steps:

Open Settings: File > Preferences > Settings (or press Ctrl+,)
In the Settings search box, type: terminal.integrated.defaultProfile.windows
From the dropdown, pick “Command Prompt” or “Git Bash” (not PowerShell)
Restart Cursor

This should fix the serialize binary: invalid int 32: 4294967295 error. It’s a known PowerShell bug, and the team is working on a fix.

Let me know if it helped.

Ayberk_Bulbul · January 6, 2026, 10:02am

Another cmd not help

deanrie · January 6, 2026, 2:02pm

I see you’re now getting a new OOM error. This is a known issue and affects several users.

Try these steps:

Start Cursor in safe mode without extensions:
```
cursor --disable-extensions
```
If it still happens, clear workspace storage (make a backup first):
- Close Cursor
- Go to %APPDATA%\Cursor\User\workspaceStorage
- Delete the folder for your project
- Open Cursor again
If nothing helps, try a full reset (you’ll lose settings and chat history):
- Delete %APPDATA%\Cursor (make a backup first)
- Reinstall Cursor

Also, please share a bit more info:

Does it happen in all projects or only this one?
What extensions do you have installed?
Rough project size and number of files?
