I am running multiple profiles on windows using the workaround of

–user-data-dir=“%USERPROFILE%\.cursor-personal”

All used to work fine until today it suddenly keeps giving me permission errors as follows:

If I run normally

0 [main] bash (14984) C:\Program Files\Git\bin\..\usr\bin\bash.exe: *** fatal error - couldn't create signal pipe, Win32 error 5

with stack error of

meanwhile if I run with administrator I get

Error: Failed to apply sandbox: Sandbox cannot run from an elevated administrator process. Please run Cursor without administrator privileges.

I already raised by email, but in case someone faced it and got a solution.

On the “main” cursor that isn’t profiled using the workaround, all is working fine, profiles are the ones broken.

I followed this fix here for my deleted cursor setup that happened today too Cursor - Community Forum - The official forum to discuss Cursor., and I noticed the Chat aren’t loading or working at all, but noticed it is always due to bash.exe being fully utilized but seems hanging, so it seems connected.

Now I terminated the bash.exe and suddenly all working again.

Hey, thanks for the report. This is a known issue. Sandbox isn’t fully compatible with Git Bash on Windows yet. The Win32 error 5 and the sandbox error when running as admin are both related to this.

Workaround: Cursor Settings > Agents > Terminal > turn off “Auto-run in Sandbox”. Commands will run normally with a confirmation prompt.

Good catch that killing a stuck bash.exe helps. That’s also a useful workaround when the terminal gets stuck.

The team is aware of the Sandbox + Git Bash issue. I added your report, it helps with prioritization.
