yubioath-desktop got a fix that works with both ykman version 3 and verison 4.
I have sent a MR on salsa to include the new upstream version (there are also updates in the pristine-tar and upstream branches). I have confirmed that the new version works with both ykman, and after I have updated to the current version of ykman 4 it still continues to work. Please consider uploading this rather soon to get the fix into bullseye.
