Nice hashrate. I think the 2060S needs to be clocked lower because you have some rejected shares there. It's the cuda code that is crashing, not the AMD code. I think the 2060S is clocked to high. try 7900 or 7800 memclock.
I could perhaps include a GPU # in the error message that will track wich of the gpu's that crashed the rig.
any advice to improve is welcome
