XBee Wi-Fi: XCTU - "Error writing AT parameter > Port configuration not valid.

I’ve been working on a project using an XBee Wi-Fi module in API Mode and using UART via the USB XBee Explorer board to connect to my computer.
Yesterday, I changed the baud rate from 230400 to 460800 attempting to speed up my transmission rate. After the parameter was written, XCTU displayed an error message stating: “Error writing BD parameter > Port configuration not valid.”
The module has now become completely bricked. I tried utilized the Recovery mode, but it keeps saying there is no active bootloader. When I connect the device to my computer, it is recognized by XCTU, but this error is thrown any time I attempt to read or write any parameters from the module.
I thought it might be that the baud rate was too high for the FT231x chip on the Explorer board, but the datasheet says it can handle speeds up to 3 Mbaud.
Has anyone experienced this or have a potential fix?

Please try the legacy version of XCTU: https://www.digi.com/products/xbee-rf-solutions/xctu-software/xctu#productsupport-utilities

Then try the recovery procedures here: http://knowledge.digi.com/articles/Knowledge_Base_Article/Recovery-procedure-for-XBees/?q=xbee+recovery&l=en_US&fs=Search&pn=1
at 38400 and 115200 baud. Those are the possible baud rates of the bootloader.
