Help! Pink horizontal lines showing on random images!

[Dayna30078266lq58]

I've edited in the past year with lightroom classic on my HP, but ever since I've switched to my new iMac, I will randomly get these random pink lines everywhere on random images. It usually happens on the best images so I'm hoping I can figure this out asap. Please let me know if you've seen this, or if there is something I can do to get rid of this problem. Thanks in advance. See the image below.

Defective GPU driver or corrupted file. First turn off the GPU in LrC (Preferences->Performance->Use grpahics processor set to OFF) and see if that fixes the problem. If it does not fix the problem, then the file is corrupted.
