To all those trying to get this fixed. I just have some things to try that are rather simple. unfortunatley as stated in OP, this issue can be caused by different thing so a fix for one might not work for another.
1. try different capture methods including window capture with compatibility mode enabled. this will require you to run your game in windowed mode but is one of the most fail-proof capture methods OBS has. If this works for you, then use this method until there is a driver update from nVidia/AMD/Intel. I know this isn't the best solution (and might not work) but since I dont have this error to test, this would be my number 1 guess at a solution.
2. Give OBS MP a try. https://obsproject.com/forum/threads/latest-windows-test-build-0-10-1.23342/ Not that this will fix anything but since this is a new build (from scratch I might add), it might be worth your time in testing with it as well.
For now that is all I have but if @Sabina261187 @MadVaper could give this a try and post back your results.
