Could be multiple things. Dry your filament, in an oven or special dry box if you own one. Clean your bed with warm water (no soap or alcohol/acetone)
Use a glue stick for better adhesion.
Also, if you printer support it, you can generate a level matrix to see if it is leveled.
Why no soap? I clean with dish soap to remove oils, works great.
Residual surface-contamination.
Most people don't understand how much rinsing is required to get residue all off things..
Dishwashers which have 2+ rinses seem to do a good job.
less than that doesn't work.
People .. seldom get anything as clean as a dishwasher can.
( NOT recommending that anybody put their 3-D printing bed's sheet through a dishwasher: it might well destroy its surface-chemistry, given how strong dishwasher detergents are )

I have been putting mine through the dishwasher for a few years now with zero issues so far.
