> If I plug in a USB keyboard or activate my bluetooth mouse, I can use those to log in, and then after logging in the laptop touchpad and keyboard work again.
The login screen uses Wayland but the default user session uses Xorg. Can you please test both logging into "Ubuntu" and "Ubuntu on Wayland" and tell us if one works better than the other?

Please also run these commands after logging in:
dpkg -l > allpackages.txt
journalctl -b0 > journal.txt
and send us the resulting 'allpackages.txt' and 'journal.txt'.
