I didn’t at first, but after the response from @mranderson17 I ended up doing just that. Which seems to have resolved that issue.
Prior to enabling testing/unstable repos for access to Plasma 6.1, CM was working fine on Wayland. However after the update it seems to have broken it but changing to X11 fixes the issue. So it’s likely a combination of me messing with my system and something with Plasma 6.1.
