It sounds like the buzzing noise you get due to the motor stalling because your bed is not leveled. I went through this a few weeks ago when I changed my FEP film. In reality I had changed too many things at the same time - new resin, new FEP film, new model with challenging supports. Leveling was definitely the first issue to solve as I was getting that nasty buzz. In the end I got it leveled by going through the process carefully using one sheet of paper. Elegoo emphasize the importance of the order of tightening the two socket screws and in retrospect I wonder if this might have contributed to my problem.
Once leveled I printed a 50% size rook (for speed) and it worked then tried the tricky print again and got a pretty shoddy print - combination of model being right up to the size limits for Mars, probably less than ideal supports and I think issues with Elegoo's grey resin. I probably learned bed leveling is really important and that the grey resin should be reserved for less challenging files. Haven't used my printer too much the last few weeks but probably will do something soon to scratch that itch!
