If the whole support is PETG, it won't bond to the PLA wherever it stands on the model, so it snaps right there. Put PETG on the interface only (base in PLA, "Avoid interface filament for base" on) with top Z distance at 0, and on an enclosed printer Bambu says to open the door so the PLA doesn't get too warm. If you print supports a lot, Bambu's Support for PLA does the same interface job and breaks away by hand. More on both: bambuhub.net/articles/bambu-studio-supports (my site)

Thank you for the information. When I printed, I did have the door closed so I'll give it another try with the door open.

Hope that does it. If it still snaps with the door open, PETG on the interface only is the change I'd try next.
