Hey, thanks for the report. I see the screenshot with the infinite loading. This is already the third time Excalidraw breaks after a Cursor update. The previous fixes were in v1.6.35 and at the end of December.
For debugging, can you grab a couple things?
- Open DevTools
Help -> Toggle Developer Tools, go to the Console tab, try opening a.excalidrawfile, and send a screenshot of the console. - Press
CTRL+Shift+P→ “Developer: Show Logs” → pick “Extension Host”. There may be extension load errors there.
Also, what version of the Excalidraw extension do you have installed?
I’ll pass this to the team. This is clearly a regression, and the fact it’s happening for the third time should help with prioritization.
