Issues with Quick Access when using Brave in full screen mode

Hi Dave,

This issue happens from time to time with or without external displays (I always close lid when I use external display).

I am not sure how to describe these terms properly.
Basically I believe I have only one desktop because:
1. I don't see Assign to in Options.
2. After I swiped up, clicked the plus button on the top right corner and added a new full screen this way (the default name of which would be Desktop 2, I can see the Assign to in Options.

For my case, I am talking about multiple fullscreen apps here (Brave, Slack, IntelliJ, etc.)

This happened just now again.
And I think there is a chance I am actually describing multiple cases here:

Case 1. If password is required, the QuickAccess would hide in the very first screen (the left most screen showing my desktop) waiting for password from time to time. This still happens even after I enabled Keep 1Password in the menu bar

Case 2. If password is not required, the QuickAccess can also hide in the very first screen from time to time after hitting the hot key (This issue seems to be fixed after I enabled Keep 1Password in the menu bar. Not 100% sure. I just don't see this anymore.)

Case 3. If password is not required, the QuickAccess does not show up at all with either hot key nor clicking the icon in the tray (which was set to bring up QuickAccess). I have to open the main 1Password window to make QuickAccess work again.

This is my laptop from my company, hence I cannot just send a debug zip to you.
But I am a programmer, hence if there are any steps to provide more debug info, I can do that when it happens again.

Thanks in advance.
