Research direction
Start with the Calculator plugin entry points named in the trace: Microsoft.PowerToys.Run.Plugin.Calculator.Main and CalculateEngine, then follow the startup path through PowerLauncher.SettingsReader. Reproduce the restart failure on PowerToys 0.98.0.0 and inspect whether the Mages.Core dependency is present and loaded. Done means PowerToys Run starts without the TypeInitializationException.
