Win11 22H2 - search function won't work when first letter is 'm' !?!

HI,

yesterday i updates to win 11 22H2 & also added the following 3 quality updates:

KB5018496
KB5018341
KB5018483

Now when i open the Start or Search windows from the taskbar and start with the letter 'm' it just freezes not entering the remaining letters and then closes itself.
If i start with any other character it works fine. 'M' works fine as long as it isn't the first charcter entered.
Win 11 never crashes and everything else seems ok. Searching in File Explorer or Mail is also ok, it's just Start & Search on the taskbar that is doing this.

I ran SFC Scannow & DISM restoreimage & restorehealth but no change.
Version - 22H2
OS Build - 22621.755

Anybody else seen this problem?
Any suggestions for a fix?

Thanks.
