all LUTs have disappeared from Finder folder?

I dropped some custom LUTs into ~Library/Application Support/Adobe/Common/LUTs Creative and Technical folders and now they've vanished from that folder, yet still show in Premiere?

If I search my Mac for .cube files, nothing shows up anywhere. I tried this on two machines, MacBook Pro M1 as well as MacBook Pro M4 on macOS Sequoia 15.5.

According to the FCP XML output, the LUTs being referenced are still in that folder. But when I go there, there's nothing. I tried enabling hidden files but no different. If I run a deep search in Terminal, it shows them as being there too.... but opening the folder they're not visible.

Baffled. Any ideas?
