tl;dr A workaround edit /etc/apparmor.d/abstractions/transmission-common on line 201 delete "deny" and restart apparmor.service
It's yet another Apparmor issue plaguing Transmission in Ubuntu https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2117338 This time the people who brought you Rust in essential system tools which nobody needed let alone asked for, decided that transmission shouldn't work at all out of the box. Exactly what you expect from an LTS release! Someone in his wisdom decided to explicitly prohibit access to DRI whereas it's what the software (GTK4 I presume) evidently needs.
