I have this same issue with a 5 year old Dell laptop using Intel UDH Graphics 620 along with Radeon 530 gpu onboard. I am seeing the blank, white interface screen while I am remoting into it with ScreenConnect (ConnectWise). The batch file to set Malwarebytes hardware acceleration did work but then I made the mistake of setting a password to prevent tampering, then re-enabled hardware acceleration, and yeah... I shot myself in the foot. I am now back to blank screen and the batch file does not work because the password I enabled blocks any "tampering". Arghh!! Can I parse the password inside the batch file somehow?
