OD 2.0 was the only change to my system. I reverted back to OD 1.9 (shame, since I lost the ability for a start menu button) and it's been fine since I last posted, none of the errors have happened.
Back when 2.0 was installed, I would have to manually unload/shutdown OD, restart my computer, then reload it afterwards with all my settings back on default.
I have no security apps on this computer. Only the standard Windows Firewall/Defender. I also did try uninstalling both Impulse and OD twice and didn't fix it.
