The earlier question was asked for android studio, which is not exactly same as Windows IntelliJ, I guess! – Brewmaster

Answer 1

After third restart, it worked automatically, I don't know the reason.

Yes. it is really a very strange behaviour. But it is true. In my case it worked after the second start with the error message. – Bomke

Sometimes this problem cause because you have unsupported JDK version. This method didn't work for me. Intellij IDEA supports java 8. So i remove all the java version on my laptop and then intall java 8 using $sudo apt-get install openjdk-8-jdk – Alienate

it did not work for me. refer https://intellij-support.jetbrains.com/hc/en-us/community/posts/360004973960-Critical-Internal-Error-on-Startup-of-IntelliJ-IDEA-Cannot-Lock-System-Folders-. This helped me. I executed netsh winsock reset suggested by Serge Baranov and it worked. – Biblio

Made fourth attempt, it didn't work for me. – Surpassing

@Sameer Khan as for me the only helped way was a installation of new version with "uninstall previous and install new one by keeping old settings" option checked. Then added lost plugins . – Warmblooded

For me, I deleted one of the plugins which was incompatible with the version of PyCharm. – Lathrope

Yes, i just restarted my computer again and then it got fixed, oops :) – Gablet
