Assertions/errors about IsMapping()

Hi, we're running the Rider Package 3.0.31 (latest) against Unity 2022.3.21 and are getting these errors, does anyone know how we might clear these please?

Assertion failed on expression: 'IsMapping()'
Tried to get mapping information from scalar node

Both happen at

We're running multiple flavors of Rider (2022.1.2, 2022.2.3, 2022.3.1) if it helps.

This is happening for MacOS as well as Windows. On my MacOS box, my Rider is installed at:

/Applications/Rider.app/Contents/MacOS

Does anyone know what is causing this error? These warnings are making it hard for non-engineers from reporting actual problems in our game

Start with the stack trace entries in Rider/Editor/Util/FileSystemUtil.cs:20 and Rider/Editor/RiderScriptEditor.cs:79, 376, and 33. Reproduce the initialization path on Unity 2022.3.21 with the Rider package and inspect how the installation path is resolved on macOS and Windows. Done means the assertions no longer appear during editor initialization while Rider detection still works.
