I’ve done the following things now:

Unsuccessful:

Upgrade from Ubuntu 20.04 to 21.04. This did not solve the issue.

Successful:

Manually uninstall and install the latest amdgpu package from
https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-
linux-21-20. Specifically, I downloaded amdgpu-
pro-21.20-1271047-ubuntu-20.04.tar.xz and installed it via the amdgpu-
install binary. This seems to have solved the issue. I reckon there is a
good chance that it was rather uninstalling and reinstalling the driver
than installing a specific version of it, but that I can’t tell with
certainty.

Title:
  [amdgpu] Locked Ubuntu is frozen and cannot be unlocked

Status in linux-hwe-5.13 package in Ubuntu:
  Confirmed

Bug description:
  After locking Ubuntu and leaving it unattended for a while, the
  operating system cannot be unlocked anymore. No means of user input
  (e.g. typing on the keyboard, moving the mouse) produce the lock
  screen and I have to shut down my computer by pressing down the power
  button. The attached monitor does not receive a signal from the
  computer during these attempts.

  This started to happen several weeks ago and worked without a problem
  before then.

  Due to the nature of this issue, I can neither report any errors
  occurring nor can I observe any other out of the ordinary things from
  happening. Thus, I don’t know which package is causing the issue.
  Also, this issue happens every time I leave the computer unattended
  for a longer time and lock it. However, locking it and triggering an
  input immediately after does produce the lock screen, so the lock
  screen seems to work in principle.

  Description:  Ubuntu 20.04.4 LTS
  Release:      20.04
