Firmware 3.9.1 Blocks on LCD
I just did a Firmware upgrade to 3.9.1. Printer was was working fine except for Octoprint emergence stop error (Temp to Low). So I updated to 3.9.1. Now on my LCD I am seeing square blocks were the characters should be. See attached. Does. anyone have a suggestion what the issue could be?

I went though the troubleshooting guide and it mentioned the squares would come up if I loaded the wrong firmware for my model. I selected
V3.9.1 MK3S (September 21, 2020)
I do not have the MMU. Isn't this prusa3d_fw_MK3S_3_9_1_3518.hex the correct one for a Prusa I3 MKS?
