The game will open as normal but periodically, itll just freeze and not respond. Itll go on for maybe 10-15 seconds then go back to normal, before freezing again a few minutes later and so on. Ive tried clearing cache and reinstalling it and even going back a version but its still the same.
This smells very strongly of an antivirus problem. Make sure your antivirus isn't registering any false positives for BYOND.
Ive checked through my antivirus and it doesnt have BYOND flagged, neither does windows defender or anything
I'd still try turning off your antivirus for a bit and see if the freeze still happens.
