Capture card freezing

[ChildOfRagnarok]

I got a MiraBox HSV321 capture card on the recommendation of another streamer because they said it plays nice with Retrotink, which Elgato cards might not always do. My problem, however, is that it usually freezes within an hour or two of use, and after this happens, OBS stops responding when I try to exit the program.
It seems like the "11:30:44.635: Device 'Digitalt ljudgränssnitt (MiraBox Video Capture)' invalidated. Retrying" bit is key, because it happens every time, but I'm not sure what causes it.

I'm including the log file and a USB device viewer screen cap. Sorry for the Swedishness.

Start OBS in Admin mode

Thanks for your reply. I tried running OBS in admin mode, and it didn't make any difference.

check the temps of the card many of the cina cards overheat after a time !

It's never gotten alarmingly hot, so I don't think overheating is the issue here.

Update: I installed OBS on a separate computer and plugged the Mirabox into that, and it ran for 13 hours without a hitch. Furthermore, looking at USBDeview, it's clear that the card actually disconnects from the computer and then reconnects, so maybe there's an overload. I'll have to look into this further.

Final update: Turns out the entire problem for me was caused by me keeping my customary gazillion Chrome tabs open at once. Shutting down Chrome while streaming has kept the Mirabox card running like clockwork ever since.
