Description of the problem

Game crashes during startup

new AR was supposed to release alongside new LV, it did not. This is almost certainly your issue.

how would it be my issue

It's a turn of phrase saying that "this is the issue you are having". however, the fix is simply to roll back for now.

oh im stupid sorry

So fix for this issue is literally just wait for new AR update? kind of sad

What's kind of sad is people are expecting updates when you don't know peoples personal life. You don't know how much time they have to allocate to working on a project that they do in their free time. I've locked this issue for the time being.
