Lightroom Classic 14.5.1 keeps crashing

[Jeff30880822tufg]

Ok this has been happening for a couple of days now. I can drop in my RAW photos and all is fine. Then I usually apply my preset to a photo and then apply it to all of them, that is when it freezes and I have to close it. I am working off of SSD's, plenty of RAM and storage. 

I have tried to reinstall 2 times, I have tried all different kind of option changes and nothing works. I have so much work to do and I cant do anything. Please let me know if there is anything you can think of.

Thank you

That's the latest Game Ready driver, which Nvidia and Adobe doesn't recommend for creative apps like LR. (Game Ready drivers don't receive as much testing with creative apps.) Instead, install the recommended Studio driver:

I have found that LrC is painfully slow applying presets.  I sometimes apply a preset to a hundred or more files and LrC goes non-reponsive for several minutes.  It has not crashed and will eventually complete the task.  I start the Task Manager and see that LrC is consuming ~10% of the CPU, and eventually comes back to life.  LrC has many performance issues that make it a pain to use.
