Yes, this happens for both the installed version and portable version. I had tried both versions with the previous Drafft ver but just now re-attempted with the drafft-Installer-1.4.2-win-x64 version. The error messages appear to be the same. Some new info is that while doing other tasks like starting a new dialogue, I also saw another error appeared, an image of which is attached.
I verified that the app.asar file is in the resources directory at that path and is 433,794 KB in size. The path makes it look like the file is being used like a directory folder, but it's just an ASAR file. That might be intentional, but mentioning it just in case, that app.asar is a file and not a directory for me.
