CR-6 SE glass build plate - no lifting possible
I have had similar issues, and I have learned three tricks:

Some slicers (i.e. Cura) let you specify the height of your first layer, and I have found that slowly incrementing up from 0.16 mm by 0.2 mm to find the sweet spot of adhesion without warping. Every brand/type is different. But, usually, for me, fall between 0.18-0.22 mm.

Blue painters tape. If you don't need the glass flat finish of printing directly to glass, I always use blue tape. It makes for great adhesion, and also easy removal of super stuck prints, and you can just peel it off the build plate. With blue tape, I tend to add 2-3 °C to the bed temp.

Glue sticks (instead of hairspray). But, Elmer's glue sticks that go on purple and dry clear. When you use these, if a print is stuck, you just need to spritz some water around the print. The print and the glue will wick the water under the print, and reconstitute the glue. Once the glue is tacky again, the print will pop right off. The only downside is a slight texture to the print and not glossy glass flat.


The reason I like the colored glue, as it reconstitutes it activates the cobalt chloride and turns purple again. This is great for knowing when it is good to start printing again. And also tends to become less of a sticky mess than hairspray.
