"auto adjusting please wait" then nothing on 5.10.0-8-amd64 (4.19.0-17-amd64 works)

I upgraded my Dell Optiplex 755 to Debian Bullseye from Debian Buster. The upgrade went fine, but it just gives a blank screen using the newer kernel option (5.10.0-8-amd64). Instead, it simply says, "auto adjusting please wait", and then the blank screen. However, it does work properly work when I boot with kernel 4.19.0-17-amd64 (which I'm using to currently type this).

Any idea how to fix this so that the default kernel boot option (5.10.0-8-amd64) works?
