Doesn't this issue may be related with extra files that osx packs on zipped files? I tried to create a .love file using terminal and passing the '-X' flag, like so:
This will create a zipped .love file with everything on current folder except for git-related stuff, '.DS' osx-related stuff and any other .love file that might appear on current folder structure (to avoid self-adding .love). The '-X' flag on end excludes extra files that osx could add on zipped file.
This worked fine for me (fused and non-fused), might work fine for you too
