22.3 won't boot after kernel and/or firmware updates

After updating linux-firmware to 20240318.git3b128b60-0ubuntu2.27 I can get past the Lenovo screen to the LM logo, but the field for the decryption password doesn't appear.

Restarting from the hanging LM logo screen after this happens, the GRUB menu appears after the Lenovo screen, and then I'm able to boot and decrypt using an earlier kernel.

I suppose I could just not update these things, but that seems like it might not be the best idea (and I may not have all my facts straight or explained things very well, I'm a little tired at the moment). I've Timeshifted back to before those updates for now. Anyway, any suggestions?
