Working* 1.16.2, broken 1.17.0 and later.
The issue is that fff times out fatally after 5 sec. when I run opencode in ~/ and not a project directory.
I have OneDrive installed and a large library of 10000 files across 1800 folders. When the startup scan hits ~/Library it dies.
Ways it could be fixed:
- scan over 5 sec changed to non-fatal error and accept partial results
- background the scan
- create exclude / async config option where a user could set ~/Library/CloudStorage
- expose timeout setting rather than hardcode / magic number 5 sec.

This issue might be a duplicate of existing issues. Please check:
~/Librarycontains large number of files — same symptom of startup failure due to large home directory on macOSFSEventStreamSetExclusionPathsblocks 21–35s when HOME has large directories — deeper root cause analysis of the same startup hang, likely the same underlying issue as reported hereIf your issue is specifically about the fff 5-second timeout being fatal (vs. a UI blocking issue), it may be a distinct code path worth tracking separately. Please take a look and let us know if one of the above covers your case.

Sure, these are all related issues and likely there are far more, but no action has been taken. The symptom is this case is different since it crashes the TUI on startup after 6 sec

I think 1.17.3 is fixing this.

@ozhanozen yep! looks like they employed async approach and added the ability to disable with
