Objects spazzing out and Physgun not working

I recently have installed Garrys mod again to play. But whenever I spawn objects about 90% of them from simple Half life 2 doors and windows or a PHX square it won’t let me move them or rotate. I can rotate or move a tiny bit then it will lock up and the object won’t move. I have not frozen the objects or anything like that.

But besides that some objects upon spawning will spazz out. Spawning the half life 2 vehicles they start flipping in the air nonstop and fling around uncontrollably.

I think you pirated Gmod, because this never happens to anyone. Did you no collide the whole map by accident by any chance?
