git fatal: failed to read object xxx: Invalid argument

I got this error while having Malwarebytes running. A PC reboot did not help. Stopping the Malwarebytes process fixed it, though. Therefore, try disabling/stopping your virus scanner since that might also cause this problem.

Finally I was able to fix this issue. I think issue happened when my computer shutdown due to power cut.

I was able to commit any changes in any of my local branch. This means my pack file is no corrupted but some refs are invalid.

Back up your .git first. Then I use git fsck command

$ git fsck --full
error: inflate: data stream error (unknown compression method)
error: unable to unpack 38fe6f16c7e8246d61150f0bc42629dbb532b5ce header

I deleted the file .git/objects/38/fe6f16c7e8246d61150f0bc42629dbb532b5ce and continuing these steps until I get following output:

Now I removed all three refs (.git/refs/remotes/origin/master, .git/refs/remotes/origin/staging, .git/refs/remotes/origin/development)

Voila! Now I was able to pull and push!

P.S. learned from here
