Could not install Arduino AVR platform: Error: Could not find platform

Clean install of Arduino IDE on Mac OS X Ventura, M1 and get the following error. For me, it means the Nano (legacy R3) board isn't showing up so I can't program. Any ideas? I also tried downloading the Intel version of the IDE, that didn't help either.

Could not install Arduino AVR platform: Error: Could not find platform.

I've seen people say uninstall antivirus, that did not help. I have tried the ARM and the Intel versions of the package, that did not help. It does work fine on my Intel MacBook though.

Seems Ventura is causing a few issues for mac users.
Per may be able to explain a little more detail.

I'm not quite sure what the issue is, but I uninstalled it again, cleaned out the files in ~/Documents/Arduino and ~/Library/Arduino15 and then reinstalled. This time it did load successfully.

I do have my Documents folder synced with iCloud, not sure if there was something in there it didn't like.
