P:Camera Raw 16.4 and \ key reverting to default

Hi there,

Some basic info:

OS: Win 11 Pro

Cam Raw: 16.4

Ps Beta: 25.12

Issues:

- After I adjusted settings and played around with the "Lens Blur," it will reset all the adjusted settings (e.g., brightness, contrast, mask, etc.) when I tried to view the original/edited using "\" key. I've tried to restart the Ps Beta, and it won't make any changes. It gets annoying when I forgot this bug existing, all the modified settings were gone. And, I cannot reverse to previous step (ctrl + z).  

Please fix it!

Cheers,

Jasper
