Getting a slicing error on Up Studio 2.6.49 Windows

This just started recently. I did a remove and reinstall and got one print out of it then it went back to this slicer error.

Please do not tell me to go to UP3. So far I hate the new software and just want my printer to work.

what are you doing before you get the slicer error? which model? what setting? what printer?

Tried with different STL’s, same settings as I’ve always used and Box+
