i converted it to 1920-2743 but no luck, i also tried converting the PNG image to a JPEG but still no luck. i wonder why my other images in the timeline dont have this issue? 


This is very unusual.

The next thing I would try is using the PNG file in an After Effects project.  Match what you are doing in Premiere Pro.  Render using the "Best Settings" Render Settings template and the "High Quality" Output Module template.  Assuming that renders at the expected image quality, import that into your Premiere Pro project.

That is unexpected.

 

What is the frame size of the PNG and the frame size of the Sequence?

 

Also, which version of Premiere Pro and which version of macOS?

the frame size of the PNG is significantly higher at 7000 × 10000. the sequence size is 1920 by 1080 apple pro res 422HQ. its just strange how fuzzy it looks for a 1920 by 1080 resolution. shlouldnt it look much clearer at that high resoulution? the version of premier pro im using is 23.4.0 (build 56). my macbook pro is macOS monterey version 12.3.1

Check that "Use Maximum Render Quality" is enabled under the Video options of Premiere Pro or Media Encoder.

Is there an alpha layer on those png's?

Search about it online. It's an extra layer, quite frequently used in graphics png's, for masking/image control. And can be either pre-multiplied or not ... which is a bit harder to grasp at first. But if there's an alpha, not being properly handled in Premiere, you can get edge effects among other things.
