I played Arc Raiders again for the first time for a couple of months and I was kicked out because I used “Prohibited software” with the error code ARAV1011. Earlier I have never had any issues.
It turned out that it is a problem with Denuvo anti-cheat. The solution is to change to Proton Experimental.
In this case they added Denuvo after the game was launched.
