Hey, @Paul L39. Welcome to the Lightroom Community. I'll need more info to help you figure this out.

Please share the system info from Lightroom Help > System info > Copy & paste into a text document > upload & attach here.

Test some variables like:

• Unplug any external peripherals & use wired input devices.
• Temporarily, unplug extra displays & only keep one active at a time. 

Head here to check if one of the errors matches what you see: https://adobe.ly/3VfIdHK

Let me know how it goes. Thanks!

Your machine has two GPUs: the power-saving Intel® UHD Graphics 770 and the high-performance Nvidia RTX 3080. The Nvidia GPU drivers are also dated. Check the conversation here & check the steps shared: https://adobe.ly/4beRF4F

If this does not help, head here to troubleshoot GPU issues: https://adobe.ly/3WNU2Wg.

Let me know how it goes. 

Thanks!
