I don't really know how this error keeps popping up. It probably has to do with one of the plugins. Did you start a fresh save?
I'm pretty certain this happens when the game isn't running in WebGL mode, which ironically can happen on newer devices more easily with the version of the runtime included in RPG Maker.
I had this problem too, since I was running the game using Proton and that doesn't give you hardware acceleration in a browser. I pasted the current Linux version of NW.js over it (adjusting package.json to have a non-empty name) and that was fine.
I think you can force the game into Canvas mode using the Community Basic plugin, which should let you debug the issue.
To make the game run in WebGL mode on more systems, you can replace the runtime with a current 'normal' version from https://nwjs.io/downloads/. This also improves the performance considerably on all systems, as the runtime that comes with MV is from 2018 and Chromium is about double the version number now.
