Windows 10: WinRT: WriteClientCharacteristicConfigurationDescriptorAsync no more works on Win11

Good Morning,I have a native C++ DLL managing BLE Bluetooth Low Energey connection who use the internal Bluetooth card of the computer. All works fine on Win10, I never had any problem connecting or reconnecting a device since 2019. Then I pass under Win11 and none of the function used after discover services seems to work. I never received the callback of the function: - GetCharacteristicsWithCacheModeAsync - GetDescriptorsWithCacheModeAsync - WriteClientCharacteristicConfigurationDescriptorAsyncSo I change the two first function to the equivalent function without cache mode and

Snip & Sketch - saving to Desktop sometimes works and sometimes does Not work (Win11)

On Win11 Snip & Sketch sometimes copies from the clipboard to the desktop and sometimes does Not

copy to the Desktop. The failed copies are listed in the recent action list, but when accessed Win11 gives

the error that "file has been moved"....

So I went into Settings to check that "Autocopy to Clipboard" was On

I noticed that there was also a setting for "Save Snips" which gives a confirmation

box when doing a save - so I set this to On

Somehow confirming the save seems to have fixed the problem, adding a step is a drag, but

at least now snip & sketch has been working every time

 

Win11 upgrade not coming

If you checked again my previous replies, you can see ASUS re-installed my new notebook a even newer Win10 Home installation. After this 2nd time installation, I only did these to the toy:

1. installed chrome
   
2. changed its display brightness
   
3. changed wallpaper
   

After your previous suggestion, the 1 month temp McAfee was gone.

I can't figure out why I can't upgrade to Win11 for such a new notebook. Newer notebook will come with Win11 natively

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
