3.12.1.5686 worked
Stock mk3s assembled by Prusa. Had a 'Thermal Anomaly with the 3.12.0 firmware.
Installed 3.12.1.3686 and got a 'Thermal Anomaly' at the same point as 3.12.0, although the fan speed was different.
Was just thinking of pressing the reset button to try again when the thermal calibration continued and eventually came up as successful.

RE:
I have a mk3s+ with silicone sock and 5 bone stock mk3s+ at a school.
All of them goes to Thermal Anomaly with 3.12.1 after students upgraded. They don't run octoprint or anything.
Unfortunately after all the errors and annoying beeping they can't use the printer. When they try to print Thermal anomaly comes again.
Me and the students don't have the time to "play" around with this.
Earlier I tried the beta versions on my home printer and got the error so I just thought there was something wrong with it.
But now five more experience the same issue. We reverted to 3.11 and will not upgrade anymore.
