Research direction

Reproduce the warnings by running LogMonitor.exe in a container based on mcr.microsoft.com/dotnet/framework/runtime:4.8 with the example JSON configuration from this repository. Start by inspecting the LogMonitor event-log rendering path and the reported errors 122 and 15033. Done means event-log events are written to STDOUT without rendering warnings or failures.
