De noise issue!

Im getting these bright coloured pixels in white areas of the image every single time I use De noise!!! Im am using RAW files too… Also when using Gigapixel Al, it never works with lightroom!! It always crashes or takes ages to load and even then it doesnt and I have to force quit lightroom and Gigapixel!! This is ridiculous as I am using a new mac with the M1 processor so there is no excuse as to why I am running into these issues!!.. I have re installed and still run into the same issues!!! Very disappointed in this product!! Can anyone relate to these issues I’m having?
