Zoom keeps asking me for Access to Microphone when the options are already on to Accept

I have uploaded latest Zoom Version am using Windows 11 again which I have just updated and I am using Zoom for first time next week with a Virtual course , the Video works fine but every time I go to access the Microphone to switch on it asks me to go to Settings to let Zoom have Access to Microphone - Both Tabs in Settings are set to accept microphone for Apps and other users.  The correct microphone is listed on Zoom so it has found it OK but just will not access it.  I have been into Device Manager and checked Microphone in there and there were to check boxes ticked for certain apps to take priority on the Microphone which I unchecked but still it does not accept.  Anyone else come across this problem ??
