0x80070057 error after deploying to the hololens


I genuinely don't even know where to start.

This problem started occurring after I installed the mrtk v2.0. Before that I was able to deploy without any issue.

The error I'm getting is a pop-up with this text:

Unable to start debugging.

Operation not supported. Unknown error: 0x80070057.

Like so:

Solution

  • The solution ended up being re-targeting the solution to sdk version 17763 inside visual studio. Still building with 18362 in unity.

    Thank you @davidkline-ms for suggesting trying this.
