Occured problem result in the app not working. Windows will close this app and let you know if there are known ways to solve this problem.

I checked idea 32 bit version. It works. 64 bit doesn't. I have windows 64 bit.

Try switching to a different Java version: https://intellij-support.jetbrains.com/hc/articles/206544879.
See if disabling antivirus/firewall helps.
