Same. My (<1 month old, very fresh/clean) Debian 10 install used a non-standard MBR on GPT boot that instead of a distinct boot partition instead used arbitrarily located bootlists for locating partitions. After upgrading to 11 (bullseye) a few months ago I could no longer boot beyond grub2... unless I picked the old 4.19 kernel from 10.
After a lot of testing old snapshot kernels and bit of git bisect and compiling I figured out the support for this non-standard boot was removed sometime around kernel 5.6.0. As of right now I'm still stuck on 4.19.
So... if you're doing MBR boot still on modern GPT disks, be careful upgrading your linux (any flavor).
