Cannot install libraries MacOS 11.0.1 Big Sur / Arduino IDE 1.8.13

Hi Folks,
I cannot seem to install libraries, as above, and cannot compile my sketches since I cannot include my libraries. Examples compiled fine. This feels like a bug to me, probably due to Big Sur breaking something.

Can anyone replicate this?

BigSur broke a LOT of things

Arduino engineers became aware of the larger picture this morning but don’t expect any quick fix for SNAPples mistake.

If bigsur can be rolled back you may want to try that ?

Also the SEARCH for “big sur” on this forum may bring you a couple of work arounds worth playing with.
