After update to firmware 3.9.3 printer stops after choosing print from SD

I did the update without problems with Slicer Version 2.2. When I tried printing I got the stop after klicking to the first model. the I updated the slicer to 2.3 and updated updated the firmware again. The problem is not solved yet. Can anybody help me please?

I did the update again and then tried to change the language to german on the printer - this caused also a shut down.

The installation of the update had no errors. What can be the root cause. Thanks in advance.

Also a factory reset did not help. I also had to wait for about 15 seconds till the factory reset display appeared.  I now have strange letters on the display when I want to change the  language. The printer starts up regular but when I want to calibrate I have again strange letters on the display.

Now I installed version 3.9.2 and everything works. If I have time I will try 3.9.3 again.

Probably another case of https://github.com/prusa3d/Prusa-Firmware/issues/2954 . For now going back to 3.9.2 seems to be the only solution.

Yes I had the same screens. My Prusa was delivered November 2020.

Thank you very much for the answer.
