F0 is not allowed, that means go to the kitchen but do not leave the couch

Open the sliced gcode it might be in your slicer user gcode section

it happens when the first layer is printed, then it just stops and reports the speed error - im pretty new at this g-code thing 🤣

it always worked, but then that error came out of nowhere

As said open a gcode file that has the error and search for it! Depending on the position in the file it could have different reasons

Or did you play with the speed multiplier during that print
