In my experience, TPU benefits from a higher first layer - it prefers being just "deposited" by the nozzle instead of slightly squished like for PLA and PETG. You can try raising your Z adjustment by 0.02 - 0.05mm and see if that makes it easier to remove.
If you work with transparent TPU and don't want it to turn white, print slow and cold.
Model Collapse is already starting to be a problem on current-gen models
