Mission Planner Crashed before start

Hi guys. I have a problem with mission planner. it works quite well with my computer (Windows 10 system), but after an autonomous update of mission planner. It crashed when i click the mission planner and ask me to press any key to exit. (Error screenshot below)

What i tried is:
1.uninstall and reinstall the mission planner
2.Reinstalled the aerial narrow front.

Could anyone help me with this problem ? Thank you in advance.

According to log something is wrong with baudrate.

Go to My documents/Mission Planner and take a look at config.xml. Change baudrate value to something general like 115200 or 57600. Or even remove this file if change doesnt work.

That works ! Thank you very much !
