Illogical Error in IntelliJ Community Edition

Hello, I recently found a strange error in IntelliJ that reports an illogical error:

However, the program still runs normally:Is there anyway to resolve this "error" within the code editor? It is extremely misleading and annoying.

In case if you are wondering about this error, this error has not appeared for me in the past. The only reason that I can think of leading to this error would be the fact that my computer happened to have a Critical_Process_Failure error (blue screen error) while I was editing code in IntelliJ.
