I've been having this problem for a week. In my case I boot up, the monitor switches to Racing mode, and I have to try multiple times to turn it off without it immediately reverting. Then I'm okay for the rest of my session.
Today I discovered something: I can trigger the problem by turning Bluetooth off and on. Doing so pushes me back into Racing mode, and, as on initial start-up, I have to try multiple times to get out of it.
I looked for any Bluetooth related drivers from the past six months or so, and the only one was Realtek Wireless Bluetooth Adapter. Rolling it back hasn't made the problem go away. But perhaps this is information someone might use to find a solution.

Processor: AMD Ryzen 7 5700G
