Your problem is (most likely) with the ZIP file. Not all .zip files are the same. Don’t compress the ZIP file; just use it for storage. If you’re compressing it with Windows 11, go to the options and select ‘Store’ instead of ‘Compress.’ That should solve your problem. By the way, they changed this about two months ago, but didn’t announce it. I had to upload the same asset four times before I figured out what the bot was having trouble with.
