Is it an issue related to Adaptive Cards?

No.

What is the PWD impact?

User Experience:

When elements lack alt text, it can significantly hinder the accessibility of the content for these users. Screen readers rely on alt text to convey the meaning and context of images to users who cannot view them visually. Without alt text, screen reader users may miss important information or context provided by the images.

Note:

User credentials should NOT be included in the bug.
