MV can be 1.5.x or 1.6.x, but if you open the console log, you should see your version of NWJS and PIXI version
that my base throw in there by default.
if NWJS is 0.29, than update it, you can do so when checking here (0.48.4 is what I recommended, but feel free
to take the higher one.
See here how to update NWJS.
if it still fails, let me know.
updating pixi is optional find here the 4.8.9 and place this inside your lib folder (as well in the locations of the steam install folder.
do the same with NWJS so they both take them on a new project creation.
if your MV ever update again, this will be reverted back and should be redone again.
notify if it still fails after NWJS update.
