Bump sound - Fill mask

Pure gramatical: Are there spelling mistakes in this?
Please correct, but keep the same words.

When I'm working wih adjustement layers, I always make a rough selection (mostly lasso tool) for the part I will be working on.
Then I fill the mask completly black (fore-or background color, depending what is what (Cmd-D)
And when the mask is black I do the finer painting in of the mask in a white brush.

65% of the time I get the 'Bump' sound, so Photoshop can not exectute my command. (To fill the mask black). 
...Because there is something selected for typing, somewhere!?
 (Either a hue/saturation value, a Color balance value, or whatever that automaticaly selects the parameter value of that adjustement layer. 

I can override this by switching from one tool to another.
Or by switching to another program on my comuter, not Photoshop. 

But this is SO-VERY-annoying, and I loose time.

Is there a solution to this please??

It's the same problem in Photoshop Beta as in Photoshop v27.0.
I mostly work in Beta, and 1 or 2 versions ago the problem seemed better. But it is back.

Please assist if you know how to solve this? 
Thank you very much 🙏

Ps: I have never deleted my preferences because I’m scared of loosing all the prefereces that I build up and finetuned over the years. Maybe this is a solution?
If so, how exactly do I do this without the risk of loosing any of the settings?
