Windows 10: Latest win10 update no longer uses nightmode?

I use night mode full time to reduce eye strain while I'm at the computer, and I only disable it manually if I need to verify the color or something. Last night I updated my PC to the latest version and now night mode is disabled. When I try to navigate to settings > display, the settings app freezes and then crashes. I can navigate the rest of the settings app without issue.If anyone has workarounds to modify display settings or other night mode tools would appreciate any tips. :Windows versionEdition Windows 10 HomeVersion 21H1OS build 19043.1586Experience Windows Feature Experience Pack

What is the latest stable build of Win10 ?

Does the Win10 update's "keep my files":
1.) Remove Firefox Mozilla's saved user+pass list ?
2.) Remove HP laptop's pre-installed drivers & programs like: HP utility, HP cool sense and such...
3.) I have also a online-paid MsOffice 2013 and update probably removes it... Do I just pick the serial number and use it again ?
