Mp3tag allows you to filter by %_cover_mimetype%, but I don't know if using image/png as the mime type would show those files, since it shows image/jpeg in the top pane of your screenshot. And filtering by image/jpeg might show a lot more files than what you want.
Unfortunately, it does not allow you to filter by the cover art description field. But it may still be better than trying to examine each file individually.

it loves and support PNG but the problem is that there is jpeg stream data in the field COVERART and a mime type different from the one included (not stream data) picture.
the problem is i need to find which file have different info between the ream image embeded and the mimetype !
and (most important) which files have stream data picture !!!!?? Even mp3tag does not clean/erase this stream pictuire when i use the delete function. -
Then you have to clean your files manually
by
1. saving the covert art
2. loading the pic in an editor
3. saving it
4. importing it back to your mp3
I use Tag & Rename for this -
My best guess is that the image file(s) that were used for the cover art had a .JPG extension, but actually contained PNG image data. So when they were added to the MP3 files, it set %_cover_mimetype% as image/jpeg because of the filename, and whatever program was used to add the cover art allowed it because it recognized the file as a valid image without checking the %_cover_mimetype%. Software with stricter rules will throw up the error – like yours did – because the actual image data and the %_cover_mimetype% don't match.
If you open such an image file with IrfanView, it asks if you want to correct the extension.
I'm not actually familiar with mp3tag, other than briefly experimenting with its search function for the sake of this thread. I have been using ID3-TagIt for years. It makes it very easy to add, remove, and extract artwork on MP3 files (and contrary to the first review that shows up on the page, it does work just fine even in Windows 10). But its search capabilities aren't as powerful as mp3tag's.

hi,
thank you for the tips, so i try.
i try to find the files using the mp3tag filter.
but i can't find the right function to use.
i would use this filter :
%LOG% IS exist_field() : to find evey mp3 with 'LOG' extend fields (or meta field..)
but the function exist_field() does not appear in the list.
is there another way to build such filter expression ?
i search in the helper file C:\Program Files (x86)\Mp3tag\help\main_filter.html, but there is no exemple to "how to find a fiel with the field existence XXXX".
i even tested the filter $len(%_COVERART%)" GREATER 40000" but it did not return the good result.
i tested too :
NOT <LOG> MISSING but not working
also
<LOG> PRESENT but not working
My first need is to find them (amonst thousands files) , so at least i will deal with them one by one to clean the fields. -
Coverfields are probably binary attachments
so text functions may no work on them

There is an option to tag cover resizing and conversion of pngs to jpg -
So I did a little experiment, and this might help you IF the cover art descriptions in the offending files contain at least a section of identical characters, even if the entire descriptions aren't identical.
To set up my test, I manually added the description Freemake\Amazing Grace.png to the file I have been using as an example here...
Which then shows up as a text string in the MP3 file...
I then open a command prompt (cmd.exe) and use the findstr (Find String) command to search for files containing the string "Freemake", and out of the 231 possible files, that file shows up. Unlike the Windows search function, which is limited to standard text-type files (TXT, DOC, etc.) when searching file contents, the findstr command searches all files.
The options I used for the command are:- /I - Specifies that the search is not to be case-sensitive.
- /M - Prints only the filename if a file contains a match.
- /S - Searches for matching files in the current directory and all subdirectories.
- *.* - Wildcard symbols to search all files
You would only need to search for a short substring – maybe just the "4aaqskzjrgabaqaaaqabaad" from the beginning of the string (with the /I option, you don't need to worry about which letters are upper or lower case) – just as I only searched for the word "Freemake".Do or do not.

it is ok, i solved the problem.
mpt3tag can search in a whole folder with the filter "COVERART PRESENT" !
and it runs fine !!! -
