Just a quick fix/workaround for something I bumped into with OBS this past few days - for some reason, the Hotkeys (Shortcut Keys that you press to start Recording, Take Screenshots, etc) seemed to stop working once you took the focus off of OBS itself. For example, if I started OBS, then started a game, and hit the keyboard key that was configured for OBS to Record (while it was in the background), it didn't do anything (eg. / to start recording). I did figure it out though, it was a real easy fix for now; so I wanted to share it here.
There was a Windows Update recently [for me] and so I thought maybe OBS needed more Permissions or something; so I just ran OBS in Administrator Mode - and it worked!
All you have to do is Right-Click the Icon that starts up OBS and choose "Run As Administrator" (possibly under More > Run As Administrator, for example, if using the Start Menu for launching OBS). That's it!
Now you should find that you can start up a game and/or ALT+TAB to the game, leave OBS running in the background, and OBS will faithfully start Recording/Taking Screenshots/etc again.
Sorry I haven't posted for some time now; my own illness (not COVID) has been acting up this year. A lot. Anyway, HTH
