Maybe not THE answer  but it s definitely AN answer   If nothing else is working for you  go the nuclear option   Close IDEA and delete the       IntelliJIdea system  directory using your local file system tools   The  IntelliJIdea directory is usually found in your home directory   Your IDE configuration is in the       IntelliJIdea config  directory  so it should be fine   Obviously  this is not the  IDEA  way to do it and would be completely unsupported by JetBrains   Also - I don t use Android Studio so I dunno if this will cause problems  but there you go     It s worked for me before when I ve had problems getting IDEA to start and nothing else works to get me going  Maybe back up your entire  IntelliJIdea directory if you have a morbid fear of losing all your work    lt

Depending on the version you are running  It is basically the same just go to  File -  Invalidate caches  then restart Intellij or File -  Invalidate caches   Restart  The main difference is that in older versions you had to manually restart as cache files are not removed until you restart  The newer versions will ask if you also want to restart       As seen here on this official Jetbrains help page    You can also try delete caches manually in the system folder for your installed version  The location of this folder depends on your OS and version installed    Windows Vista  7  8  10  lt SYSTEM DRIVE gt  Users  lt USER ACCOUNT NAME gt    lt PRODUCT gt  lt VERSION gt   Linux Unix     lt PRODUCT gt  lt VERSION gt   Mac OS   Library Caches  lt PRODUCT gt  lt VERSION gt   Read this for more details on cache locations

In addition to the  Intellij  files  and invalidating the cache  if you really want to clear everything out  then also delete the  idea folder and   iml per-project files that IntelliJ also generates
