After selecting a Profile for Fujifilm X-H1 RAF files, selecting "Reset All Settings" from the menu bar (or using associated keyboard shortcut), immediately crashes Lightroom. This does not happen after making other corrections to the image, only when applying a Profile.
I've tested this with multiple RAFs from my X-H1 and it happens every time. It also happens with DNGs converted from X-H1 RAFs. I've also tested with photos from my Fuji X-T1 and it *does not* happen with those. This is all within the same Lightroom catalog.
We're really sorry for all the hassle. Could you please update Lightroom to 7.3.1 version via Creative Cloud desktop app and check if that helps.
If updating Lightroom doesn't help then, turn off the GPU from the Lightroom preferences and let us know if that helps.
Go to Lightroom > Preferences > Performance > Uncheck GPU > Restart Lightroom.
