the full or mini base is required here.
I suspect your version of NWJS is default (0.29.0) and I highly recommend update it to 0.48.4+
which is also the default which MZ uses.
All my plugins require the minimum of the NWJS to 0.48.0+ in order to work correctly.
Pixi version default is 4.5.4 and is optional to upgrade to 4.8.9 for MV.
after the update it should work as it uses ES6 and is not really working for NWJS 0.29.0.
