'System.IO.FileNotFoundException' with message 'Could not load file or assembly 'Roslynator.Core, Version=4.1.2.0

[MalcolmEllis]

Product and Version Used: Roslynator 2022 v.4.1.2 - VS2022 17.4.1, Windows 10 Pro 21H2

Steps to Reproduce: Seems to be tied to whether the VS setting (text editor/c#/advanced) 'run code analysis in separate process' is on, and that the last update of VS 2022 turned that 'on' by default. Switching that off stops the error. Also, seems to have the same underlying cause as this: https://community.sonarsource.com/t/ad0001-errors-system-io-filenotfoundexception-could-not-load-file-or-assembly-sonaranalyzer-cfg/71341/15 Someone in that thread mentioned the 'separate process' switch as a workaround. Sonar have now fixed their extension so I tried toggling the separate process back on and got this error message from Roslynator. Quite possible that this warning was happening before but the Sonar extension caused so many thousands of its warnings that I didn't notice the Roslynator one in the deluge.

Actual Behavior:
Warning AD0001 Analyzer 'Roslynator.CSharp.Analysis.ValueTypeObjectIsNeverEqualToNullAnalyzer' threw an exception of type 'System.IO.FileNotFoundException' with message 'Could not load file or assembly 'Roslynator.Core, Version=4.1.2.0, Culture=neutral, PublicKeyToken=926ea54d246a765e'.
