my question: electron-userland/electron-builder#9107
possible root cause:

• electron-builder debug build logs reveal missing files (app-512.png) and missing locals/ folder
• error possibly originating in react-build?

Attempted fix in:
https://github.com/MartinBarker/RenderTune/releases/tag/v2.0.9

still getting error, fix attempt did not work, need to check build logs with

DEBUG=electron-builder electron-builder build > build_debug.log
