I have been having some project export issues (project file size is about 1.2gb), when I try to export my project at the moment via nw.js desktop build i get a "out of memory" error at the end of the project export (my computer has 32gb of ram) and if i try to export an android cordova project I get a "Build Failed" with no errors. Would you by any chance know what may be causing this? I assumed it was file size as it was working fine before the project was over 1gb
