When you send an email to support you get an automated response with a request id. Did you sent those mails with your mail client or with the feedback button?
Your mail provider should have given you a response within 7 days, if the mail is undeliverable. You did check the spam filter of your mail provider / client, did you?
Also, please reconsider uploading different versions as different projects. It makes you look like a spammer and, well, you quoted the faq: "Avoid uploading ‘reskins’, or many project pages for minor changes"
Another thought, maybe your mail provider is on a blackhole list.
Oh, and it does not help, that your game flags as malware. You might have been reported for that, and it might take some time for itch staff to investigate if it is a false positive. Godot exe packing should not be used in my opinion. It only creates strife and makes people ignore positive scanner results.
