When the attached 3D file is selected to be imported using the “Import 3D” built-in studio plugin, memory skyrockets to super high values, rising until a computer freeze/crash.
The 3D importer window appears, then studio stays frozen and the memory usage rises.
From my testing, this can be reproduced in a fresh baseplate file 100% of the time.
It can be reproduced even with all manually installed plugins disabled.
