Windows 11, Adobe Photoshop 2022 -- I had the issue before the most recent update, and now it's still occurring. Whenever I try to export a 64 grid point LUT -- File > Export > Color Lookup Tables -- Photoshop just crashes. I just tried a 32 grid point LUT and it worked. My computer's fast enough to edit Red raw 6K footage, so I don't think that's the issue. Any ideas of what's going wrong?
When Photoshop crashes, this is the first thing to do, try resetting your Photoshop preferences. Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) immediately after launching Photoshop. You will be prompted to delete the current settings. You can also reset preferences upon a quit if Photoshop is running by going into General Preferences>General>Reset on Quit.
