Find the offending line (or lines) that contain the part "compiler.cpp.extra_flags\": \"-std=c++17" and delete them. Next save the file and start the IDE.

Alternatively you can delete the file; it will be recreated but you will no longer have the additional boards manager URLs.

Note
I suspect that you just did an incorrect copy.

I have moved your topic to the dedicated IDE 2.x category of the forum.
