LrC slow startup or not reponding at all

[AgaNagA]

Suddenly my LrC 9.3 takes a very long time to start up and sometimes it refuses to startup at all. 

I have turned off the Graphics acceleration and GPU for display settings, turning those on only gives me slow performance and other problems.
I'm working with 2 catalogs, one on an external drive with 11951 pictures, and one my D drive with less then 4500 pictures. They both started taking like 2 minutes to startup if they even do. 
When clicking on a picture while it starts up it shows me the splash screen again and on the upper bar it says that lightroom is not reponding. There is no strange CPU or RAM usage when checking the task manager. 
I'm using a Logitech MX Master 3 but the plugin is not installed and never have been.

I'm hoping for somebody to help me with this

Kind regards

Installed Plugins:
1) LogiOptions

According to your system info, LogiOptions is installed. I think it gets installed automatically when it detects that LR is installed.

It might well be the cause of your problem.

Go to File > Plugin manager, and disable it.

Hi, do you have custom settings for lightroom on MX Master?

[AgaNagA]

I disabled the Logitech options and it seems to work

I have LrC ver 10.1.1 and Win 10 and had been experiencing very slow startup.

I disabled the “Logitech Download Assistant” under the STARTUP TAB in Task Manager.
LrC now starts the way it used to. Here’s a little more info on that:
