Considering Ryzen 2000 series (Zen+) is just a slightly tweaked Ryzen 1000 (Zen) architecture, it makes zero sense for them to not be able to handle Windows 11 without crashing, so it sounds like AMD has basically requested them to be blacklisted. Even though the Ryzen 3000 series is much faster and works on 300 series motherboards, for those of us who bought in early having to replace a perfectly good CPU that sold for up to $500 3 years ago is crazy.
It's also crazy because it excludes the Threadripper 1000 series, as it's also Zen based, and someone who may have dropped $1000 on a 1950X on a platform which is only upgradable to a still near $1000 or more Threadripper 2000 series, so those people -really- got the shaft...and I was very close to being one of those after my first 1800X died.
But the good news is that Windows 11 doesn't bring anything game changing to the table unless you're Intel, it means new licenses for businesses whose software doesn't jump OS versions, and for the significant percentage of users who aren't computer literate and will be as lost with the new changes to the Windows 11 UI as they were from 7 to 10 (and we all know people like that), so blocking the upgrade is a good thing.
