I tried updating using my /etc/apt/sources.list file set to "stable" and tried logging in. I could not log in to MATE, I downloaded jwm and tried selecting that, and I could log in.
I then changed /etc/apt/sources.list and replaced "stable" with "testing", then I ran as root, "apt-get update" and "apt-get upgrade". Now I can log in to MATE. I changed my /etc/apt/sources.list back to "stable" by replacing "testing" with "stable" and then ran "apt-get update" and "apt-get upgrade" a whole bunch of packages were held back but it upgraded what could be safely upgraded. I can now run MATE from Debian Stable / Bullseye. Eventually the Stable repositories will contain the fixes that are in the Testing repositories and everything will be OK. Great!
