Unity Version Control break my project

I don’t know what I did but my project broke after I updated the changeset. My code is not working properly. I tried to change back to the previous changeset and then in the changeset tab it shows "
Undo this change+meta. Undo selected change. 2. Skip. Sign in was not completed."

Then I clicked the play button immediately and the code worked fine. But after I click on another tab, the editor just resets and the problem appears again. Does anyone have this problem? I’m struggling for hours and can’t fix this. Please help me!

What is your Unity version and Version Control package version?
