@uweschmitt do you have this git config setting enabled in your system?
https://git-scm.com/docs/git-config#Documentation/git-config.txt-corefsmonitor

If so, could you make an exception for the .devbox/ repository in your devbox project folder so that it is disabled for that directory (and sub directories).

For our internal nix functionality, we currently create a git repository. However, that will be going away in the next release of Devbox...the PR for removing it (coincidentally) was merged recently.

Thaks a lot for the quick response! In addition to setting core.fsmonitor to false, I also had to delete the existing .devbox/gen/flake/.git/fsmonitor--daemon.ipc file.
