Reproduction steps:
1. Set up Google Drive File Stream (Instructions: https://www.scu.edu/technology/get-connected/g-suite/learning-google-drive/file-stream/windows-users---google-drive-file-stream-install/)
2. In the Google Drive File Stream create a project which uses Asset Import Pipeline V2 and attempt to open it

Reproducible with: 2019.2.0a5, 2019.2.21f1, 2019.3.6f1, 2020.1.0b2, 2020.2.0a4
Not reproducible with: 2019.2.0a4 (Asset Import Pipeline V2 unavailable)
Didn't test with older versions as the crash seems to reproduce only when the project is being opened using Asset Import Pipeline V2

Notes:
- With older versions, which don't use Asset Import Pipeline V2 by default, the bug is reproducible by going to Edit -> Project Settings -> Editor -> Asset Pipeline and choosing Asset Import Pipeline V2 to be used for the project
- The crash seems to affect not only Google Drive File Stream, but similar other services, as well as OneDrive and VMs using HGFS Network Drives
- Some users report that they cannot create and open new projects in these same locations due to this crash, but we're unable to reproduce that behaviour
