m18 R2, BTTray error, unable to start the Bluetooth stack service

Hi there over the past few days, I have noticed this error whenever I reboot my machine. No idea why this suddenly started happening. At the same time I have noticed Windows always goes to the Startup Settings screen and I have to press enter to load the OS and continue as normal. All BT devices seem to connect/work ok, but it is driving me around the twist. I have this on an Alienware m18 R2 running Windows 11 Business. The upgrade to Business is automatic due to the Microsoft 365 subscription we have here at work. I know I am lucky to have this as my work machine, but I think as I own the company, this is a little treat for me, why not? It's the least I can do for myself. Nice to be able to drop into a gaming session at the end of as long day. Just recovering from a massive stroke, and thought it would treat myself. Anyway, I justify the high sec with the fact that I do most of my academic research and analysis on this machine. 

Any help gratefully received.
