According to Apple, safe mode should allow you to change it.

If there’s no picture on your Mac after you change the resolution

Wait to see if the resolution resets automatically, or restart your Mac in safe mode and choose a new resolution.

Are you sure, you booted into safe mode? the procedure is a little different on Apple Silicon Macs

Start up your Mac in safe mode

Starting up your Mac in safe mode may help you diagnose problems with your Mac.

Strange.

If you have another Mac and have enabled screensharing, you could connect and change the settings. But if screensharing is not already enabled, it is not much help.

Turn Mac screen sharing on or off

On your Mac, use screen sharing to connect to another Mac on your network and display its screen on your Mac.

Alternative you could try connecting to another display/tv and hope it doesn't remember what settings was used.

I guess cables and monitor are working since you have bootscreen. But you try completely powering off both Mini and monitor, hoping that will make a difference.

the only way to fix this was to reinstall or buy a screen with 75Hz refresh rate, which is what i did; it's not the same problem as the @changing resloution@ exactly. many thanks to those who commented.

Connecting a second display to your mini likely would have been able to solve the issue without replacing the main display.
