SOLIDWORKS is busy running a command

Hello

Why do I often get this message, even with assemblies of barely 10 pieces.

I have a PC with 32GB of RAM, INTEL I7 9th gen.

Sometimes SW indicates that he was unable to open the PDM Bas.

The task manager indicates no response. 

It is loaded 500MB for memory in general.

Thanks in advance,
