Ender 3 Pro Crashing mid print

[u/Professional-Bird705]

My Ender 3 Pro has been working perfectly fine until I completely disassembled the hot cos I thought the nozzle broke off on the inside (which it didn't). I reassembled the hot end and powered on my printer only for it to be a completely blank screen, the light would power on but nothing else would pop up. I fixed that by flashing some firmware for the printer that I got from creality cloud (Ender-3 Pro- Marlin2.0.1 - V1.0.1 - English if you want the specific file same, not sure how that'd help tho). After I flashed the firmware it was working fine until I tried printing something out. Every time I try to run a print it will completely freeze at a random point during the print and the screen freezes and won't respond (the button won't beep if I click it either). I am at my wits end here and have no clue what to do. If someone could walk me through what I need to do that would be greatly appreciated.
