@Mr-Android said in Oops! Plutonium T6 ran into a problem and must be closed.:

Do you have any overlay's running?
Rivertuner
MSI Afterburner
Discord overlay
etc?

If so, try turning them off and see if it helps.

Oh... it's working. Thank's you so much, Mr. Android!
I don’t know why, but even with RivaTuner the game worked stably. After 2019, BO2 just stopped working. Thank you again.

I have been trying to fix this problem for more than one week and all to no avail. At first there was an Unhandled exception caught problem on the license, then here... an unknown error. Can you help with the first and second problem?
