It seems that indeed the BinLib version cause to this issue.
Please try to recover the PLC as follow:
Use COM1 RS232 115200 baud rate 2sec time out
Connect 6 wire cable instead of the 4 wire cable.
Reboot the PLC
The PLC should beep > tap once to stop the beeping
Go to VisiLogic>communication & O/S, the 4th tab is system modes
Check the communication by clicking on the GET button
If you have a communication>Switch to Factory BOOT
Go to O/S tab>check Download only the BinLib by clicking on the Advance button>BinLib (only)
If the download will success, then replace to 4 wire back and download the BOOT and then the O/S.
