Hi there, I'm having an issue similar to one I've seen others post with opening Lightroom. Every time I click on anything in the app after launch it crashes without an error message. If I don't click on anything, it crashes anyway in about 10-15 seconds. I suspect it could be a graphics card issue as I'm running an aftermarket card (RTX 3060ti), but I'm unable to even open Preferences within Lightroom to try disabling the GPU.
Thanks for getting back to me so quickly. I'm using Windows 10 Pro, version 19044.1706, and Lightroom 5.3. My GPU drivers are set to auto-update so I should have the latest version installed, I'll try the fix you suggested tomorrow and let you know the results!
