intellibot: Fatal error with PyCharm Community edition 2018.1.4

I installed “IntelliBot @SeleniumLibrary Patched”, but when I am running the PyCharm IDE with the plugin, It always throw the fatal error. I don’t know why, but I brought the error log here.

Can you investigate on this, I very new to Python language, Now I using PyCharm IDE for doing a Robot Framework run for test website.

And sorry if issue is duplicated in some way. I did search for “Fatal error” keyword. But it didn’t appear anything.
