Problems with the editor

[Zeffo]

I worked on the map for a few hours and after saving what I had done and logging back in a few hours later I started having problems (I only worked on the map with the units, I didn't add anything or create a specific trigger.
On other maps I don't have this problem.)
I go into the editor and move the mouse on the map for 5 seconds and then it just freezes
Even if I don't move the mouse and go somewhere else, the same thing happens
I reinstalled Warcraft and it still does the same does anyone know where the problem comes from and can help me.

Hello !
Is there customs units with blp textures model on the map ?
If you place cutoms units with blp textures directly on the map and if it is not a campaign map this problem happen (for me)
