I’m still running 2408 Build 16.0.17928.20114 (32 Bit), no problems here.
You can try to downgrade your Office version with this command (run a cmd as Administrator):
“C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe” /update user updatetoversion=16.0.17928.20114
and check if it’s working again.
Btw, you can delay the updates by setting a registry key, see:

I set it to “Deferred” to stick to the “Semi-Annual Enterprise Channel”
