Stumbled into an issue that have been able to slightly fix. Although I haven't found a clean and safe solution yet.

I have used Ultra on my pc and there it has worked without issue. But on my laptop, it has given some issues. There is gives The requested resource is in use (0x800700AA), after putting ultra local and doing some tests I have found that _kernelSession.EnableKernelProvider( throws the exception.

The way I can currently get around it is by disabling and enabling windows defender, and then it doesn't throw it until I restart the laptop. The application I try to profile has been excluded by defender in both cases.

Don't think if this is fixable by ultra outside of some error handling/ documentation. so, I'm partly posting this so others can spend less time on this.
