Thank you for trying to help!
lol, this isn't getting anymore clear...
spent the day working then went to launch FFXIV and OBS.
Tried restarting FFXIV and OBS seperatly and together nothing worked here's a sample of the logs.
Rebooted and opened chrome, ffxiv, obs and it's working at the title screen...
Close and Reopen OBS repeatedly and it hooks in instantly at this time...
no idea what's breaking it. When I was troubleshooting this on Friday or Saturday (logs gone due to reinstall of OBS after dumping the folders to make sure I got it all on uninstall) Reboot was definitely not working but I had some success by switching to Astroneer which worked and back lol I mean changing the game capture specifically object.... I don't see any reason why that would work which is why I'm thinking the issue is more of an intermittent issue but only presents when I'm hooking into FFXIV.
Oh and as a side note StreamLabs OBS also coudln't connect to FFXIV when OBS couldn't connect, obviously they both don't work simultaneously, but right now I can switch between them with no issue.... Basically just trying everything I can think of even looked at windows defender threat lot, curious if it could be the issue but don't see anything jumping out there.
At this point I'm in a see what happens tomorrow, mode. If it does fail again I'll see if starting OBS with --verbose gives more descriptive logs.
