Added a new plugin library to my unity project and when Assets are imported, I get the following stack trace:

Could you please give us dll and pdb files, which cause the problem? If you don't want to share it publicly, please send it Ivan.Shakhov at jetbrains.com. Thanks!

[van800]

Does the error show up many times or just once right after installing the new plugin?

[ajwalters]

Just once. I will email you the DLL that was being imported that caused the error

[van800]

I would need dll and pdb. Please send to Ivan.Shakhov@jetbrains.com Thanks!

[van800]

Ah, I see you have already sent it. Thank you!
