Cursor cannot load WSL after update

[thibauld (Thibauld Favre)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I just updated Cursor to latest version (3.5.17) and it just won’t reload. The IDE shows up but terminal cannot load. The only clue I have is that it seems stuck in an infinite loop because every 20s or so, I see (very briefly, hard to catch) the popup I am attaching.

Steps to Reproduce

Update cursor to v3.5.17

Expected Behavior

Cursor to update without a glitch so that I can continue working.

Does this stop you from using Cursor

Yes - Cursor is unusable

More information:

1. When I close Cursor, it also hangs. I need to “Close Anyway”

2. I tried restarting Cursor from WSL. Didn’t help. Exact same issue.

Update: I rebooted the PC. It solved the issue.

“In doubt? Reboot!”
