Bug A meta data file exists but its folder render-pipelines.universal/Custom can't be found

Starting with 2021.1.b5, in b5 and b6 I get this warning every 3 seconds, and every time it opens a modal progress bar, fails, and then retries forever. Which makes the editor pretty much unusable.

The warning existed before, but only was printed in the console once.



Text reads: "A meta data file (.meta) exists but its folder 'Packages/com.unity.render-pipelines.universal/Custom' can't be found, and has been created. Empty directories cannot be stored in version control, so it's assumed that the meta data file is for an empty directory in version control. When moving or deleting folders outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it."

Spoiler: Packages/manifest.json

P.S: Reported as Case 1314080.

 

Some additional info on this case:


Right after opening Unity, every three seconds forever, a Unity Package Manager "Resolving assets" pops up, together with the console entry.

 

This is ongoing with 2021.1.0b10 (starting with b5), only that in b10, the console text is not emitted anymore:

(repeats every 3 seconds – deleting the Library folder does not help)

 

No worries and thanks so much for the help!
