[0.61.2] Can't bundle/assemble release, debug works

I updated my project to 0.61.2 to make use of hermes to shrink my app size and now I can’t generate a release version. I tested with a new app and the same error happens:

A problem occurred starting process 'command '..\..\node_modules\hermes-engine\win64-bin\hermes''

I also get this other error in my project, didn’t try to reproduce it here. I get either one

error ENOENT: no such file or directory, open 'C:\Users\Thales\myOtherProject\android\app\build\intermediates\sourcemaps\react\release\index.android.bundle.packager.map'

I’ve tried cleaning, rebuilding, updating the CLI, recreating node_modules, checking the path to hermes-engine and still nothing.
