Laptop touchpad freezes when using Lightroom

[A35507714vdt8]

Whenever I have Lightroom CC (version 7.1.2, but also the same happened when I tested 7.0 and 6.5) running my laptop's (DELL Precision 5560 with 11th Gen Intel(R) Core(TM) i7-11850H @ 2.50GHz 2.50 GHz , Windows 10 Pro) touchpad starts freezing. It'll get stuck for about 2-10 seconds, does not respond to anything, until it unfreezes and works just fine for a minute or two. Doesn't matter whether I'm using Lightroom actively or it's just open in the background and I'm using some other program, freezing still happens. However, if I plug in an external mouse there is no issue whatsoever. If I have Lightroom open and the laptop goes to sleep the whole touchpad disappears from device manager and only reappears upon restart when it's reinstalled. I have now had this issue for about a month, before that Lightroom had an issue with crashing every few minutes, but that was resolved with the newest update. Before that Lightroom and everything else was working perfectly. The issue is not with the touchpad itself, touchpad and keyboard were replaced a while ago to see if that would solve the issue.

Hey, @A35507714vdt8. Welcome to the Lightroom Community. I'll need more info to help you figure this out. Are you working with multiple displays? Please share the System info from Lightroom Help > System info > Copy & paste into a text document and attach it here. 

You have two GPUs on your machine. The power-saving Intel UHD Graphics & the high-performance Nvidia RTX A2000. Please try these two suggestions:

1 - Update the graphics drivers using Intel's & Nvidia's auto-detect programs.

2 - Follow step 6 in the content here to configure the default GPU for Lightroom: https://adobe.ly/3V1iq6S

This should directly help how Lightroom works.

Let me know how it goes. Thanks!
