Can't upload zipped electron app

[BluestarLp]

I can't upload my zipped electron app to the github releases.
It always gives me the error Something went really wrong, and we can’t process that file.
It is within the size limitation of 2GB.
In particular their seems to be a problem with the main .exe file (which is 130MB ca. 70MB compressed) but I do not know why.
When I tried uploading the zipped file with the .exe file removed it worked. But since I am using electron the making of that file is
out of my control and is done by electron-forge.
I have already tried using different browsers (firefox and chrome)
I am just asking if anyone expirienced a similar problem and can help me.
Thanks in advance.
