And yeah, forgot about 3rd one: Sometimes UI test cannot even pass the login flow, via ASWebAuthenticationSession, the login form just disappears but nothing happens. This happens like in 1 of 4 tests runs randomly, never happens locally

Nothing, I've submitted 2 major Xcode Cloud issues to Apple 2 month ago, still no response on a single one. One of them was about that keyboard-related freeze. I've met several reports on similar freezes around the net, none of them had any solutions. Feels like ppl are not too much into UI testing on cloud to get enough of those bugs for Apple to start doing something with that, but as this is happening with 100% repro and cannot be dodged by any kind of tricks/refactoring I hope this will become a big enough deal for someone to resolve this. I bet the repro shouldn't be too hard. Had anyone tried to isolate the bug in a sandbox project?

I know it may freeze even before the keyboard is show, like you can just print application.textFields.firstMatch and test freezes during this, you don't even has to perform some UI action, just a lookup freezes. It's a huge issues and it's up for like half of the year, I've submitted several reports about this to Feedback Assistant + Developer support email. The only response I've got through to my huge detailed request for help - I've got a link to https://developer.apple.com/support/xcode/ website with a comment "We highly recommend that you check out this article". That's it! I got all them reports case numbers, all them feedback assistant cases - noone cares. I'm literally left without any help, not just me, lots of people are reporting the same issue, noone every found a solution or got assisted by Apple
