Unable to read staged files: Unsupported git index version 3, only 1 and 2 are supported

Issue

Any idea of workarounds or when this can be fixed?

If you can point me in the direction of the issue, I can also take a look.

Workaround for me was (but didn't work)

❯ git update-index --show-index-version
3

❯ git update-index --index-version=2

❯ git update-index --show-index-version
3

Version and model info
