Photoshop: PNG has black background after Image/Trim since new update

I always trim my products to save disk space but the last couple of days when I trim something I get a black background with a png file.

I went back in and trimmed it again (it didn't trim anything) but when I closed it and reopened it the black background was gone. 

Here is my original post:

It looks like this might be a Windows problem with either their latest update, or PS and its latest update. I'm on a Mac, and of the participants in the thread, I'm not seeing this issue at all now.

I am experiencing the same problem as well. When viewing my trimmed png files through Photoshop, the png files have a black background. Some of my purchased png files when view through Photoshop also have a black background. I have to open the file in Photoshop and re trim, save, to get rid of the background when viewing through Photoshop

I only noticed this after the latest Photoshop update 20.0.5 but at the same time Windows updated to version 1903 so I can't pinpoint which program is responsible.

My Driver is up to date.

I cannot reproduce this with Save As, Export As, or Save for Web.

My steps are:

1. New transparent document
2. Paint a bit
3. Image > Trim
4. Use either Save As, Export As, or Save for Web to save a PNG file
5. Close the document
6. File > Open... and examine the thumbnail for the file you just saved.

I've not been able to save a file with a black background.

Jeffrey Thanks so much for responding.

I need to clarify -

The .png file saves as a .png file should, with a transparent background, whether I use Save As, Export As, or Save for Web. The image retains its transparency as it should.

It's only when viewing some thumbnails which are actually transparent .png images through File Explorer via Photoshop that these images have a black background but I don't think Photoshop is responsible. I think it's a problem with File Explorer.

I've gone through and viewed the majority of my transparent images with File Explorer and actually have found about a dozen of my transparent files have a black background. Opening them up in Photoshop they're still transparent, which shows that there must be a glitch with File Explorer.

Re-saving these files as transparent png, gets rid of the problem so you don't see the black background, instead you see the transparency as it should.

I honestly think this issue arose after Windows 1903 Update as I had not seen this issue prior to the update.

But having the Windows 1903 Update and Photoshop 20.0.5 confused the issue with me.
