Stuck on previous/older Insider version

Greetings,

I'm on the Beta channel and my issue is that I can't update my version,'Windows 11 Insider Preview Feature Update (26220.7070) (repair version). When I run Windows Update it tells me I'm up to date but when I click on the Windows Insider Programme there is message which says "A newer build is available in Windows..." and "Not seeing a newer build?" I hit the button "Open Windows Update". When I do that and run the updater I'm told I'm up to date. AGAIN...

I've tried all sorts of fixes, command scripts, 

WuReset2.0

 Windows Trouble shooters don't work

I don't really want to do a clean install, my machine is part of my digital audio workstation with tones of software (200+ plugins and libraries)
which takes several days to put the whole thing together again.



Thanks for any advice
