Thank you for the verification.
This is a purchased material 3D file called archmodels.
It was opened once with R17 and saved.
In other words, it wasn't made by me.

(I bought this in 2014, which means that the original data was made in C4D at that time.)
Similar errors occur with other trees in this collection.
> Does an error occur in everything I made with R17?
No error will occur in all.
Specific files, material collection files, etc.
This is another material collection file. It freezes when you select a `ball` object. Even if you select `glass` or null, it will not freeze.

With R17, even if you select ball, it will not freeze.
