I've had two persistent issues that have existed for the last two or three beta versions of the software. Both issues happen on my setup at work, which is a Dell USB-C dock with two Dell monitors attached.

The first issue occurs when connecting to the dock where it gives me an error saying that Windows cannot reserve space for the multi-monitor taskbar and needs to be restarted. I've only ever received this error on this setup, and never when connecting to any of my other monitor setups (which also use multi-monitor taskbars).

The second issue occurs when I try to apply the monitor profile for this location (my work setup). I get a general failure error, and it says that it failed to call SetDisplayConfig. I've completed deleted the profile more than once, and created a new one, but the error continues to persist. I can apply the wallpaper profile and window position profile individually and it works fine, but when trying to set the monitor configuration (which would in turn set both of those), the error happens every time.

Any help in getting to the bottom of these issues would be appreciated!

I just rolled back to version 9.9 as suggested, and the error still occurs, but it now says "Failed to call SetDisplayConfig".
