Solidworks crashes when I orient my assembly

Since Friday, my solidworks crashes every time I hold the middle mouse button to orient the view of my assembly when before everything was fine.

I'm on solidworks 2016 and to try to solve the problem, I switched to SP 4.0 this morning. Does anyone have any idea where this can come from???

Thank you.

 

It 's an assembly with solidworks or an import

If it's an import have you managed to transform it into a flawless part

If it's at this moment that it crashes, it's because your import is not clean and you can't convert it

Hello

It happens to me too. It's when I have shared functions in multiple rooms and with configurations; all of which makes the assembly heavier. To remedy this, I block the functions of parts like these:
