PLA Sticking to Bed

I’m a noob at 3D printing— I got my Ender3 S1 a little under a month ago. I’ve had great success on multiple prints using mostly default settings, up until last week. I had adhesion problems and was told it was likely my nozzle. I tried a spare nozzle and my next two prints were perfect. Since then I’ve had nothing but messy, blobby unsuccessful prints. More concerning, the prints are sticking to the bed so badly that all I can do is brutally scrape the PLA off. I’ve tried using iso alcohol but it doesn’t make much of a difference. I’ve heard acetone can damage the bed, and I don’t want to make it worse if it’s salvageable.

Is my bed cover completely ruined?
What should I do to prevent this in the future?

Thanks in advance. This is my first post on Lemmy and it’s exciting to see how quickly this community is growing!

This looks like the stock ender 3 S1 bed. If you get the prints off you might actually pull the texture of the metal flex plate. Mine lasted a few days before I had multiple holes.
I got a textured PEI plate and I can't complain, prints self release when the plate cools and it doesn't have any defects after almost a year and about 100kg of filament.
- Just for reference, what sort of plate did you replace it with? I’m waiting on a Creality glass PEI plate that should be here soon and I’m hoping it will be better. Still not sure how this happened in the first place but from what I read it looks like the print head was too close to the plate and it ground PLA into the bed. I was using the same settings as always and I trammed and levelled before my first print. It seems to have done this every time I tried to print this particular object— Is it possible the actual gcode from Cura could cause this?
