trying to print PLA on glass ...

Here’s another vote for glue stick on glass.
I tried blue tape and never got good results.
Then I tried hair spray and it worked but was messy and took forever to dry if I got it on too thick.
When I tried glue stick- I found the secret magic. Apply it lightly and thin- then wait for it to dry. Counter-intuitively it works much better when totally dry than when it’s tacky.
I can now just print over and over till adhesion begins to falter, then lightly apply the glue stick again and forget about adhesion problems for many prints.
Try it- you’ve got nothing to lose.

Or you could better regulate your media temperature. If the consistency is that of glue then it will stick to most things. The trick is to work at a temp that allows for a quick enough cooling of the media so it does not have a chance to stick. Or like I always say go back to powder
