Bluetooth almost mouse unusable on Windows 11 Pro 25H2 Build 26220

Since installing feature update 26220.7051 - my logitech MX master 2S lost connection. 

The cursor was not visible and mouse was not connected.  I removed the logitech dongle and tried bluetooth and still no luck.  I tried another logitech mouse - MX anywhere 3s which is blueooth, and it took me numerous attempts to get it to connect. 

I have since removed any/alll logitech software, optional drivers, reset bluetooth, revmoed all devices/re-scanned etc.    

I cannot reconnect the MX master and the MX anywhere connects but lags and every few minutes, the surcor dissapears and then comes back after about 5 seconds.

Is anyone else having bluetooth issues?  Or mouse issues?

I removed the logitech receiver as bluetooth is built in so wanted to make sure nthoingon usb was causing the issue.   

--  UPDATE : Looking at latencymon - it seems the issue may be more to do with storport.sys and stornvme.sys.  But bluetooth mouse the most obvious/most impacted.  DPC calls through the roof onboth e.g. 500k in just a few mins of boot.  Could also be various OneDrive and GoogleDrive accounts checking though.
