Today when I tried to start intellij IDEA from my desktop, it did not start, just a waiting cursor occurred and no action after that. so I tried to run it form command line and ran the idea.bat from the bin directory of Intellij installation folder: the following is the log appeared when I did this, Intellij did not open this way either.the first line of the log shows some error message:

The following was the last line of that log and then it stopped printing anything on console:

This error seems to indicate an instance of IntelliJ IDEA is already running. Perhaps in a degraded/invisible state. Try and kill all IntelliJ IDEA instances using the Task Manager or reboot your system. Then try running idea.bat again.
