Unable to parse PythonAutomationTest.uplugin: '$' is an invalid start of a value

I’ve been working smoothly in Blueprints for months, no problem. (Using UE 5.1)
Today, I tried to add a C++ project to one of my Blueprint projects; it required that I install MS Visual Studio; I installed Community 2022. Suddenly, everything pretty much exploded in my face. I can no longer even start a blank project without having the following error show up in the output window:
Unhandled exception: EpicGames.Core.JsonParseException: Unable to parse D:\Program Files\Epic\UE_5.1\Engine\Plugins\Tests\PythonAutomationTest\PythonAutomationTest.uplugin: '$' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

I’ve attempted to use ChatGPT to remove that specific library from compilation. I’ve attempted to remove the Python plugins from the editor. (now that I can actually boot a project) The C++ version I installed is 14.35.32215

Anyone know what could be causing this?

I get something similar when trying to regenerate the VS2022 project file. I also tried disabling plugins (in my case Trace*) but it didn’t change anything. Same error:

Unhandled exception: EpicGames.Core.JsonParseException: Unable to parse D:\Program Files\Epic Games\UE_5.2\Engine\Plugins\Developer\TraceSourceFiltering\TraceSourceFilters.uplugin: ‘$’ is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

Any ideas, anyone?
