Updated VS 2022 to 17.3 and now get XamarinTelementry Error

Question

I just updated my VS 2022 to v17.3 and now I get the subject error when compiling a (formally) working iOS app. The error message is:

Error       The "XamarinTelemetry" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json,     Version=13.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

I tried installing the latest version of Newtonsoft.Json even though I don't use it, but that didn't work, also tried just referencing the Newtonsoft.Json.dll, still didn't work. Tried cleaning and rebuilding, didn't work. I couldn't find any other suggestions out there, so I'm kinda at a loss as how to proceed. Anyone know whats going on here?
