Hello wonderful people!
Quite recently (<24h) I updated my Linux Mint Cinnamon workstation (running
20.3 with kernel 5.16.10-051610-generic) with a simple "sudo apt update ; sudo
apt dist-upgrade -y". After doing so, I noticed this afternoon that I could no
longer use my scripts to reach an RDS server that I manage. After running
another apt dist-upgrade -y and checking the validity of the .rdp file on a
Windows machine, I am left to believe that a library or freerdp has broken.
Below is the output in my terminal after running this command:
/opt/freerdp-nightly/bin/xfreerdp /home/tmanok/Downloads/idmrds.rdp
/u:"DOMAIN\USERNAME" /p:"REMOVED-PWD" /dynamic-resolution
I've also added some comments to this "paste" of the output:

Ok, so the RDS Server is behind a gateway, which is likely why those DNS errors
always show up and could be related to that common SSL error. The rest of the
issues appear to be .so component related. Perhaps my brand-spankin' new kernel
is to blame?
If there are any other questions, please let me know, if you would like to see
logs simply specify the path and I will be happy to provide them.
Thank you very much for enabling me to be a full-time Linux user despite having
to support Microsoft Infrastructure.
