All right I will add it here even tho I feel noone reads this but if it can help somebody it would be nice. The best solution for me overall was that I just created new profile to Arma 3 root folder by using this command on launchers commandline. "F:\Steam Games\steamapps\common\Arma 3 -profiles=Profiles" This will be the command wich makes new profile that then it's not needed to run your profile from C: path... Also copied my edited missions to the main root folder FROM C:\Users\Edizon\OneDrive\Asiakirjat\Arma 3 <--I also think that when I linked my computer to OneDrive it started causing alot of these path problems. But this I feel was my issue.

I tried switching hardware. GPU RX 580 to RX 570 and PSU from old 530W to new 750w. did not help...

It is just crashing randomly I will try tomorrow changing my GPU. Maybe it's dying? running on Sapphire Radeon RX 580 nitro+

It was not the quick access keys wich I thought it would be. I realized it MIGHT have something to do with my profile. Because I think while I am in game and try to bind some buttons. This crash might also happen again... crash after crash... this is getting on my nerves..
