git can't read file

Am 03. Nov, 2022 schwätzte Joseph Sinclair via PLUG-discuss so:

moin moin,

Thanks for the response. I ran out of time before SeaGL to work this
issue.

Finally able to get back to it.

I did this backwards and ran git gc first, then deleted the file, then ran
git gc again. Still getting an error.

Do you mean look at the objects file?

I'd gotten an error earlier pointing to an object file.

OpesHead along with ENCODERD and DURATIOND make me think this is for an
audio or video file.

Perhaps the webmB indicates the type :).

Is e7ea989038d655ba08765acad29d2110f845de the checksum of a file? If so,
how do I determine which file?

Seemingly, I can still check new work in, but I keep getting an error.

ciao,
