Intelij IDEA work slow and sometimes hang :(

hi im using i7 and 16gb for my ram, usually when i open the IDEA my laptop temperature is getting higher as like im playing a high spec game. i think this is not normal because my fellow worker, work with same spec notebook and i did not see the problem in theirs.

im using intelij idea community idea-IC-172.3968.16. and i also get this error when running the app
