Ipad Pro not charging or recognized

Hi everyone,

I'm having trouble with my iPad Pro 3rd gen, model A2377. It suddenly stopped charging. I've already replaced both the battery and the charging port, but the issue persists.

It seems to charge very slowly when in DFU mode, but it's not recognized by my computer. I'm really stuck and could use some help.

Has anyone experienced something similar or have any suggestions on what I should try next? Any advice would be greatly appreciated!
