Moisture detected in charger port.

I have moisture detected in my charging port notification. I cannot charge my phone via my USB-C nor can I use my cars Andriod Auto feature for navigation as a result.

I cleaned the port with 90% Isopropyl alcohol and a tooth flosser thingy (powered off obviously). I dried it out and the notification went away. However it has reappeared a week later when I plugged in another cable.

-I’ve tried different cables various brands and originals with no luck.

-I’ve tried clearing the USB cache.

-I’ve tried a factory reset.
