One of the common failures after using a bad charger / wet cable / simply for no good reason(this case) is a CD3215 Failure. CD3215 is a Texas Instruments chip which controls USB power including PD communication with charger. If one chip failed, MacBook does not recognize charger or provide voltage to external devices. It might even run till battery is dead. Unlike old MagSafe USB-C PD controller detects cable and charger type and sends current request. By default USBC PD provides 5v voltage which is used to generate al G3HOT rails and power CD3215.
The difference between T1 and T2 power consumption pattern is pretty important in this case: 5v, 0.2A on T2 might also indicate a firmware failure. Before playing around with T2 CD3215/17 always check if it talks a DFU mode. Check logi.wiki for more information on T2 DFU restore.
