Apart from the initial restore after a crash (which has never worked for me since I started in 4.17, I believe is a source control thing which I don’t use
I noticed, (sometimes) if you click the “restore” tabs button on the bottom right, too fast, right at editor startup it will do this. Also, sometimes when other warnings/error popups show up right as the editor first opens.
Basically, if you give it some time before you click ANYTHING, you should be good. Especially, when you get popups and warnings right when you open the editor.
