Fiji Manage Update Sites Crashing

Hello!

Completely new to Fiji - thanks in advance for any help!

Been trying to access additional plugins on Fiji, but when I click Help > Update… > Manage Update Sites, the app always crashes before I can do anything. I’m not sure what to do - I’ve reinstalled Fiji a few times with different Javas downloaded and have run into the same issue every time.

This is what the windows look like:

I’m on Mac OS 11.2.2 Big Sur, and have been downloading the Fiji zip file from Fiji/Downloads - ImageJ .

Thanks so much!
