Windows 11 Insider Preview 10.0.26058.1100 downloads but will not install

Windows updates download but fail to install.  Gets to about 75% installation then reboots and undoes any changes.  This is a recurring problem.  Last successful installation was Windows 11 Insider Preview 23601.1000 on 12.3/2023.  Now Microsoft Store does not work and some programs will not start. WordPerfect which is used daily now fails to start - WPWin21.exe - Application Error.  The application was unable to start correctly (0xc000007b).  This not the only program that gets this error.  Any help would be greatly appreciated.
