So yet again.
Le me having code review, so get into the old project that I had open a few hours ago. Le project is slow with a lot of red words and classes, ram memory was the issue, I opened too many projects at once.
We talked about intellij and the suit in general... while intellij was crashing.
Le me force/shut intellij with Task Manager.
Le me restart intellij to have again a lot red words and classes.
Le code review ends.
The funny part is that when they asked me if the company paid for intellij, I told them that I was paying it, with irony and shame.
The solution now I know is File / invalidate caches/restart.
