Failed git push leaves lingering objects

Today I was attempting to set up a development environment when I was getting this strange error

I’ve read here that fixing the issue is as simple as running

But it didn’t work for me. I eventually got the idea to log into the server that hosted the bare repository I was trying to push to, and simply deleted the ./objects/96 folder. This allowed me to push. It turns out an earlier failed push left this ./objects/96 folder lingering in the bare repository (the repository I was trying to push to)
