Ah, this might actually help troubleshoot - that icon (the red dragon) is for RPG Maker VX Ace. (VX is an unicorn, XP is a sun, RM2000/2003 is a hero with a sword iirc. MV exes should use the Minecraft-styled iso 3D hero as an icon; as for MZ, I'm not entirely sure.)
I don't have MV and MZ executables or deployed versions around, unfortunately. MV and MZ no longer use the Runtime Package (they automatically deploy the default assets) so that isn't a RTP problem, very likely nwjs and some VSCode leftover install fucking things up as nwjs implementation started with MV. (Also, from your screenshot and for your own safety, you might want to disable Microsoft trolls every default OS install with in folder settings...)
Rather old but related to your problem as RPG Maker MV/MZ nwjs deployments will rely on VS Code.
This issue seems to be present in multiple VSCode releases.

If you somehow have a conflicting VS Code install:

(if you don't use it, uninstall it)
You could also try and update your nwjs install:

Please let people know if that helped you. I'm kinda out of ideas if that still doesn't fix it.
