Rhino 7 keeps on crashing while using Subd

Rhino 7 keeps crashing while using Subd and says that there has been a ‘rhino memory allocation fail’. Now I cannot even open the files with my Subd models inside.

Hello - this has been fixed - you can get a build that has the fix by setting the ‘Update frequency’ on the ‘Updates and Statistics’ page in Options to ‘Service release candidate’ - that will get you 7.5, which should have this fix.
