This issue might be a duplicate of existing issues. Please check:

• EPERM: operation not permitted, open 'B:\~BUN\locales\en_US.json' #8441: EPERM: operation not permitted, open (similar storage permission errors on Windows)
• Random TUI freeze/hang with process continuing in background #12834: Random TUI freeze/hang with process continuing in background (similar symptoms of TUI hanging)
• Error: EBUSY: resource busy or locked, open 'C:\Users\test\.local\share\opencode\storage\part\msg_c07a553a4002p8bzxuNt6daDoG\prt_c07a562c6001jnaED4w5LAGvzE.json' #11089: EBUSY: resource busy or locked when accessing storage files (related storage access errors)

Feel free to ignore if none of these address your specific case.

Can you confirm what OS you're running? The EPERM error accessing storage is typically a Windows file locking issue.

There's an open PR (#6913) that adds retry logic for these transient file lock errors (EPERM, EBUSY, etc.) caused by antivirus or other processes. If you're on Windows, that would likely fix this.

Also related: #12834 reports similar TUI freezes in v1.1.53, though the root cause there seems different.

Can you also share:

• The full error message/stack trace if you have it
• Whether you have antivirus software running (especially FortiClient or similar)
• Does killing and restarting OpenCode always fix it?

I running on MacOS 26.2 (25C56)

As software, i have Microsoft Defender on the company laptop.

About restarting fixes, sometimes yes, but little after it comes again.

The error message, could you instruct me on how to get it? I can only see that on the TUI when working on something
