logiooptions panel pops up

Update after speaking with Logitech, and testing with a Logitech Craft Keyboard:

Summary: Close the logitech panel, close Premiere Pro, relaunch Premiere Pro, the panel will remain hidden - but still function.

Details: Logitech Options, or LogiOptions, is software that gets installed with your Logitech device.

If you have one of these 3 devices, though, Craft Keyboard, MX Master 3 (mouse) and MX Anywhere 3 (mouse) then Logitech will prompt you to install a CEP panel (Common Extensibility Protocol - meaning that a Logitech developer has written a panel extension, aka plugin, to create additional usibility with specific Adobe applications, like Premiere Pro)

That panel is designed to run hidden in the background. Right now, for example, the scroll wheel on my Logitech Craft keyboard allows me to jog through my sequence in the timeline - and I do not see the panel. HOWEVER - if I went to Window> Extensions> LogiOptions > v8.xxx,  that tiny panel will appear. And closing it will cause my Craft keyboard to stop its special functions within Premiere Pro. The solution is to not relaunch the panel, but to close Premiere Pro with the panel closed, and then reopen Premiere Pro. The panel will remain hidden, but the Logitech keyboard will continue to provide its special Premiere Pro functions.

If you do not have one the 3 Logitech devices listed above, @suginuma 's suggestion of removing the CEP panel is also valid. For example, @CrosstownAlliance-KMiller you write that you have an MX Ergo Trackball - there is no additional functionality for your device provided by the CEP panel; hide or remove the panel.

Thanks for you patience on this, and stay safe,
