Freeze when importing a specific FBX file

Asset Importers

-

Reproduction steps:
1. Open user's attached project
2. in the Project window, click on MSL_clean_NoStringblend.fbx

Expected result: Inspector shows asset information
Actual result: Editor freezes

Reproducible with: 2018.4.23f1, 2019.4.0f1, 2020.1.0b12, 2020.2.0a14

Note:
1. If the project version is changed, the freeze will occur when trying to open the project.
2. With 2019.4.0f1 the FBX was able to be selected, but when trying to reimport the asset, the editor froze.

    Resolution Note (2020.2.X):

    The supplied asset has over 2,500 animation clips on one object. This is why it won't open in Blender, Max, Motion Builder and so on.

    In Unity it does open, & the Inspector does eventually display, however it takes a very, very long time because it has to traverse 2,500 individual clips. This volume of clips is beyond what we would reasonably expect on an object, & I would suggest it's most likely an error has occurred at export or configuration time.
