P: Desktop: needs to restart to clean?

I did this and reset my preferences however upon re opening I am still promted by the "Lightroom needs to restart to clean up a few things" and still stuck in this loop.

Try resetting your preference file:

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Tried to re-install the Lightroom App but told that the Installer needs to be updated for my operating system.

Getting a slightly different problem but Lightroom doesn't want to open anymore:
Bought a new Mac M1 Mini and transferred my system to it - now everything is running in OS 11 Big Sur
Tried to open Lightroom today but it won't open.

Am told I need "Adobe Application Manager" to run the product.

Well, do I ?

Never had a problem with it before on my MacPro and I can't see how to actually get the Application Manager.

Is this a bug ?

Having the same issue in the past couple of days, having used Lightroom successfully on my Mac for a few months now. Any suggestions for a fix for Macs?

Will do, I can run all of the other Adobe products however so how do I disable my GPU in preferences. Additionally, earlier this year lightroom was bugged for me and when refreshing my license it kept saying I didn't own it however when I clicked through it always said I had and therefore I haven't been able to use it.

Recommend that you check with your video card manufacturer and ensure you are using the latest update for your GPU. 

If so, have you tried disabling your GPU in preferences?

Ive got the same issue and am on windows 10.

Are you Mac or Windows?
