Bug - remote.c:236: hashmap_put overwrote entry after hashmap_get returned NULL

When I try to push to remote git server, I got:

BUG: remote.c:236: hashmap_put overwrote entry after hashmap_get returned NULL

When I try push to another repository on the same server, it is working correctly. The problem is only with one repo.

Local Git version: 2.36.0.windows.1 Server Git version: 2.19.2

git fsck did not reveal any problem Checking object directories: 100% (256/256), done. Checking objects: 100% (23956/23956), done. Checking connectivity: 18782, done.
