Environment.FailFast

Has anyone ever encountered this when building and launching a plugin from VS?
Funny thing is that “it works on my other machine”, with no difference found in configs yet.

edit for context:
rhino opens, the _Grasshopper command runs, it fails on the grasshopper “Loading remote assembly Plugins”

'Rhino.exe' (CoreCLR: clrhost): Loaded 'C:\Users\Antoine\AppData\Roaming\Grasshopper\Libraries\dendo_v1\Libaries\DendroGH.gha'. Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.
'Rhino.exe' (CoreCLR: clrhost): Loaded 'C:\Users\Antoine\AppData\Roaming\Grasshopper\Libraries\Pug_1_1_0\Pug\Pug.gha'. Symbol loading disabled by Include/Exclude setting.
'Rhino.exe' (CoreCLR: clrhost): Loaded 'C:\Users\Antoine\AppData\Roaming\Grasshopper\Libraries\Pug_1_1_0\Pug\Tensorflow.Binding.dll'. Symbol loading disabled by Include/Exclude setting.
'Rhino.exe' (CoreCLR: clrhost): Loaded 'snyvASUNIwKRWnPCGevJTkLuYiKS'. Module was built without symbols.
An unhandled exception of type 'System.ExecutionEngineException' occurred in Pug.gha

The program '[45424] Rhino.exe' has exited with code 4294967295 (0xffffffff).

Just in case anyone gets something similar:
the plugin “Pug” was causing the issue on netcore.
