image must be at least 256x256

• Version: 19.53.4

• Target: NSIS Web Win x64 and ia32

Building my app now always results in the following error:

image C:\Users\johann.rekowski\Documents\Apps\Media-Presenter\build\icon.ico must be at least 256x256

The .ico file is 256x256, I tried also using the 1024x1024 png version of my icon in the build folder but then it applies an icon that has horribly jagged edges.

I tried downgrading (used to work with 19.53.3), but since today there is some unlocked dependency that is not compatible with 19.53.3 which causes a bunch of errors when I try to build with the downgraded version:

I have the same problem building for Mac. I’m using electron-builder 20.36.2.

@develar Problem fixed on my side with 19.53.5, thanks!
