Thank you for this question. I would suggest a factory reset of the device but make sure to make a backup. because there is a chance that an app or a setting is causing conflict on the operating system that is why you are experiencing this issues you can do this by going to Settings > General Management > Reset > Factory Reset
if your issue persists after the reset your next step is going to a Samsung service provider to get the full diagnostic of your device. they should be able to fix it too if they find a problem on the device you can look for one here https://www.samsung.com/us/support/service/locations/
hopefully, this will help with your problem

I understand your frustration with this particular charging issue. I would check if there is any lint or build up in the port as well, as this can sometimes give that moisture detected in the port error message as well following with a Factory Data Reset if that does not work.
As mentioned in the thread if it appears its not a software issue and the port is clean- then reaching out to a Samsung location near you would help to see if the device needs to be repaired.
Hope This Helps!
