Someone has already kindly offered a suggestion, and I also think it'd be a good idea to see if you can whitelist the 14dwy folder from being scanned by your antivirus program ^^ I promise there are no malicious files or malware hidden inside /gen
I doubt this is the case, but as a precaution: make sure to only download 14DWY from the official Itch page. That way, you can ensure that no sketchy, third-party websites are trying to get you to download any harmful viruses.
This also doesn't apply to you specifically (since you're using a PC), but I also want to quickly state that there is no official mobile app for 14DWY yet! So please don't download random files online or follow tutorials from accounts that aren't mine T_T
