Bug Hold on in save scene

It's frustrating and scary because this crash happens when you save a scene and there is nothing you can do to undo the damage, I just edited the UI for half an hour and when I save it "Hold on" appears again.
This makes my work simply can not be carried out.
This is definitely the biggest setback I've encountered in 6 years of using unity

I see that most people only encounter problems with shader.db, but this is a separate issue

 

The number of times I restarted unity this week was more than my total last year
