Issue with git lfs

Body

I was using git lfs for the first time and I think I made a mistake using this tool. I was working on a local feature branch. I ran following on this branch:

git lfs install
git lfs track "*.pso"
git add .gitattributes

and I kept working on this branch for many days and accumulated many commits. When the feature was code complete, I started an interactive rebase to squash my changes into 1 commit:

git rebase -i HEAD~21

This is when I got an error. The log has this message:

git-lfs/3.5.1 (GitHub; darwin arm64; go 1.21.7; git e237bb3a)
git version 2.39.2 (Apple Git-143)

$ git-lfs filter-process
Error downloading object: xxx/xxx/xxx.xxx (ca46f1a): Smudge error: Error downloading xxx/xxx/xxx.xxx (xxx): [xxx] Object does not exist on the server: [404] Object does not exist on the server

It is true this object does not exist on the server. I am not sure if it is my mistake but it shouldn't be trying to download an object that has not been pushed in the first place. I somehow managed to continue with the rebase. I don't remember the exact steps I followed but most likely I did a combination of:

1. edit .gitignore to ignore the large files being tracked by git lfs
2. also ran git config lfs.allowincompletepush true

after this I was able to push to my remote on github. but now I cannot push the lfs file no matter what I do. I keep getting errors:

$ git push origin main
Git LFS upload failed:   0% (0/1), 0 B | 0 B/s
  (missing) xxx/xxx/xxx.xxx (xxx)
hint: Your push was rejected due to missing or corrupt local objects.
hint: You can disable this check with: `git config lfs.allowincompletepush true`
Uploading LFS objects:   0% (0/1), 0 B | 0 B/s, done.

how can I fix this?

when I see something like:

commit 39 (HEAD -> origin/main, main)

does it mean the contents of .git are identical across my local and remote? what is the way out? do I have to contact someone in GitHub?
