Still, with all this my Lightroom Classic is terrible. It constantly glitches out, freezes and crashes, and even scrolling through images (24Megapixel or 42 Megapixel) it can take up to 20 seconds to load a single image in the develop module. This is extremely frustrating as I'm a professional photographer and need to edit large amounts of images in a short amount of time.
Can anyone please advise what the heck is going on here?

Please try creating a new catalog in Lightroom and let us know if it helps with the crash issue. Also, if you haven't submitted a crash report, please submit it the next time Lightroom crashes and let us know.

If you have Asus Aura, Asus Lighting service and/or Asus Framework installed and you have Windows 20 v2004 so spring/May update of 2020, then uninstall those asus software. I had the same problem and uninstalling solved it.
