Photoshop PNG exports have transparent rectangles
Hello,
When I export .PNG files, sometimes part of the image has rectangle parts that are transparent. As seen in the image below. It appears randomly in different places in the image, but it is always a rectangle and the same size. (As seen below.)

If I export the image again, the rectangle goes away.


I couldn't find any post about this issue or solution. I use the latest version of photoshop (this is happening at least for a couple of versions for me), using the latest graphics card drivers (tried different versions, game ready and studio), re-installed clean windows, and photoshop which also didn't fix the issue, also I believe project file is not the issue since it happens in other and new projects as well.
Any idea about the reason behind it and how I can fix it?
