Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

Continually hitting a oack-objects error when fetching tags in my repo. This occurs in CI during critical jobs. The issues is flaky but leads to an unreliable system.

The Error:

ERROR: Failed to fetch git tags from origin!
	Stdout:
	Stderr:
BUG: builtin/pack-objects.c:4310: should_include_obj should only be called on existing objects
error: pack-objects died of signal 6
fatal: could not finish pack-objects to repack local links
fatal: index-pack failed


What did you do before the bug happened? (Steps to reproduce your issue)

ran the following:

git fetch origin refs/tags/<version-identified>.*refs/tags/<version-identifier.*

What did you expect to happen? (Expected behavior)

tags to be fetched to the CI machine running this command 

What happened instead? (Actual behavior)

error above was thrown causing the job to fail

What's different between what you expected and what actually happened?

pretty simple...we expect the fetch to work as expected

Anything else you want to add:

we are pretty sure retries will resovle the issue but that shouldn't bne necessary. 

we upgraded git from version 2.47.0 -> 2.49.0 and then started seeing the issue so we believe this is a low level git issue itself and not our use of git in our repo
