Greetings,
You are usually safe applying feature releases to a system without affecting your attached hardware significantly. A version upgrade of the OS can be a different story. In this case, things can sometimes break.
I would recommend starting over with the printer. That is, remove the device from your system and uninstall its software. Now restart.
Drivers for the MF249dw. Windows 11 - Full installation package (Print, Scan & Fax) are here:

If you need an individual driver, Scan, Fax or a "lite" version of the printer driver, those can be found here:
