Problem with console

I have updated to last version of pycharm and updated some programs which brought me a lot of problems. Most of them are solved but I have still one issue that worked ok before but now is crashing. 

I reduced it to:

1) in console I type: import pandas as pd, I get Backend Qt5Agg is interactive backend. Turning interactive mode on. and later 1 second later Process finished with exit code -1073741819 (0xC0000005). Same with import matplotlib.pyplot as plt. But not with import datetime or pickle. Seems to be a backend problem/configuration. 

if sugestion is to reinstall Pycharm, please give me instructions

Additional information:

Windows 7

T:\Anaconda\python.exe "T:\pycharm\PyCharm Community Edition 2018.1.4\helpers\pydev\pydevconsole.py" 1050 1051
