Can't Establish a Serial Connection ICX 7150

[srb3689]

Had a power outage recently which causes a PoE failure for my APs. In the past, I've been able to establish a serial connection session using PuTTY program accessing the CLI and can return the switch to proper function.

I am not able to establish the serial connection like before. Each time I try, I get the Windows chime indicating an invalid entry.

I've uninstalled/reinstalled drivers, double checked the port details and serial line, tried different USB-C cables, unplug/replug the switch itself, restarting my machine. I'm not sure how to proceed with getting my switch to work properly.
