We also see this in our repository, when executing this line:

This is due to the experimental feature
PSNativeCommandArgumentParsing. As a workaround, you can disable the feature or control it with this variable:nohwnd commentedon Aug 30, 2021
Thanks Patrick.
Medeni Baykal (@Haplois) This should also work, when relying on scoping to reset it for us:

Just as an FYI this should be the desired behaviour as it is escaping the values correctly. It will allow you to do
my.exe '{"foo": "bar"}'without you having to manually escape the double quotes yourself. The only exceptions would be executables that don't follow the standard MS C argument escaping convention which there are some out there.
