ELegoo Mars 2 Pro won't starting printin and starts loud hum with vibration

[carverebain]

Please see the video I attached to the post. I just bought the printer yesterday, and I have only gotten the default chess pieces to print. Now, I am getting this problem. The plate moves to the bottom, and then will not start printing and it starts to hum loudly with some vibration. I think I may have accidentally pressed the down button while resetting the Zero axis, and the plate was firmly against screen. It is acting like it is not reaching its set zero, and keeps trying to move lower I think. Any help would be appreciated.
To add to this, I have tried multiple power cycles, and re-leveling and re-zeroing. Here is my reddit post where I have the video: https://www.reddit.com/r/ElegooMars/comm..._loud_hum/
