There appears to be an error in your compilation. Bytecoin Core is looking in AppData\Roaming\Bitcoin for it's data instead of AppData\Roaming\Bytecoin.
Thank you for letting me know.
I've downloaded, unzipped and run bytecoin-qt.exe in my desktop, laptop and also a fresh Windows 11 development environment in a VM; and it starts syncing with the bytecoin network fine.
I'm using Windows 11 64bit Home edition, version 23H2. I'm unable to replicate the error this end.
I'm afraid I'm going to have to trouble you for more in-depth information what's happening. Does it start syncing or just doesn't start at all? Have you tried a custom datadir path? What version of Windows are you using etc...
Classic "works on my machine" problem.
