Same is happening with me. Here’s how i fixed:
In my case, This happens when i try to import any sketchup file that has tress, flowers
or something similar. ( Maybe i could say that these are components that use, lets say, a leaf and repeat it a lot of times, like an array or particles.)
Open your SKP file in sketchup (online if you dont have installed in your system), try to locate these components, and exclude them. (this sucks when your model has a lot of tress in it. another way is edit the component, and remove eveything, then close it. you wont have to exclude each copy)
Then you will be able to import the file into blender. I dont know how to explain why this works.
