raspberry pi 4 tkinter full screen is bloked keyboard and mouse doesnt respond after booting

Question

raspberry pi4 i was coding a basic screen with a label on center with tkinter that goes full screen, with escape to close the screen, then switch label width to 1000 and text wrap (something like that to wrap characters) to 1000 then reboot the pi

now loads the screen, the label is not visible, mouse and keyboard doesnt respond

how i can get to change the code i cant even connect it to via ssh

only when pi is booting or after boots i have a 1 second to do something before the python scripts loads

maybe a keyboard shortcut but it has to be before that 1 seconds

I tried alt f4 and ctrl alt f1 but keyboard doesnt respond

only when bootting and 1s before python loads
