I encountered this while loading new filament during a print.
When the dialog message that asks you to confirm if the color of the filament is correct, and you enter Z height adjustment by pressing and holding the control knob, you are then not able to select any options to continue the print.
The fix is described in the https://github.com/prusa3d/Prusa-Firmware/issues/1196.
Both issues have the same root cause.
Unfortunately, not yet accepted.
Hi,
Thank you for the report. Bug confirmed on fw: 3.5.1.
@tdiggity Is this still an issue? If it has been fixed in a newer firmware version, please close this issue.

This now looks fixed. When a long press activates the Z height adjustment it is safe and possible to do either a long press, which does nothing, and a short press that returns to the screen that was active when Z height adjustment was activated.
I'm closing this issue as solved, thank you all.
