Short description of error
Sometimes Blender crashes opening the file, sometimes when i enter sculpt mode, sometimes crash when i start sculpting or go into edit mode, sometimes when i use lasso mask tool in sculpt mode, use the voxel remesher....
The object is important because i work on a commission - those crashes are totally not cool. :/
Exact steps for others to reproduce the error
Open the blend file and sculpt on the mesh, use lasso mask, go into edit mode. Just play around with the head model a bit. Maybe Blender even crashes on you opening the file.
