IMAGES HEAVILY DISTORTED UPON EXPORT - They appear fine while editing issue arises during export.

I am at a loss of what to do. I have NEVER had anything like this happen before.

Background - I did a photo session at a local baby group and there were around 10 mums/babies who had photos taken. It was a lovely session, everything looked great, checked my images throughout the session to ensure photos looked good. Camera settings fine. There were no issues. I edited in LRC and the images look perfect in the editing window. I export (same settings as always - will pop below) and uploaded straight to the gallery and sent. I didn't notice the issues because they looked fine in LRC. Once the galleries were out I had a Mum message about AI and when I checked the images were completely different in appearance. When I say they are so distorted it's ridiculous, some even look like there are extra fingers etc. The images do have some noise but not a ridiculous amount to have lost tonnes of detail. I haven’t used any of the generative AI features and manually reduced the noise etc. I have no clue what has happened. Of course, I now have 10 Mums very upset and my little business is now going to get a lot of negative feedback when I have worked so hard to build a really good reputation.

I have spoken to adobe over the phone and they have said there have been issues with the latest update which have affected some users. But if you are someone who has had the same issue please let me know what you have done. 

So far I have: checked for updates. uninstalled, reinstalled, reset the device then installed again and the issues have stayed. 

I love LRC but it feels like this may be the end of the road for us. Especially from what the advisor has said about the latest updates. There have also been other issues with LRC - odd previews, glitches and random closures of the program. I know that Adobe doesn’t edit the RAW images, but the originals are showing the same issue now where they weren’t previously. 

Export settings:

JPEG, 100% Quality, sRGB, Not resizing, 300PPI, Standard sharpening and I include all of the info. 

These settings have always worked perfectly for me in the past so I don’t understand what is happening. I have spoken with other photographers who have had the same/similar issues since the latest update and have now begun using editing softwares.  

Any help or advice would be great. I have also had my laptop and settings checked by someone who teaches you how to use LRC and they are at a loss too.
