Lots of good suggestions in this thread already, but long ago I used to work at a company that sold second-hand stuff where we often had to deal with stubborn labels and I haven’t seen our “nuclear option” mentioned yet. Brake cleaner, which is basically an organic solvent in a spray can, should be great on glass. Be careful with it, though, it melts some kinds of plastics. And ensure it’s used in a well-ventilated area.
Try that if the usual GooGone type stuff doesn’t work.
We also used WD40, it tended to be gentler on plastics. Though it left a greasy residue that we’d need to clean off afterward and it was pretty slow.

Brake cleaner will not only take the paint off your wall, it will start to eat it.
