Bed Temperature Resetting

doesn’t matter, just failed another print. I want to cry. got a notif on my phone that it failed to cut the filament, i come in and the head has ripped its cover off somehow and the print along with it. I have no idea why this keeps happening. I think am done with this printer. I don’t get it all. I got an amazing articulated dragon ONCE. Ive cleaned the textured plate with alcohol, i’ve upped the bed temp, I’ve turned off the aux fan. NOTHING changed, why cant I get it to print now?
