File with specific name suddenly can not be opened

Hi,

I have been working on a project for quite a time but now suddenly I can not open one file with specific name. 

In this case file Panel.vue can not be opened.

If I just rename it to whatever file can be opened.

And if I open this file and rename it back to Panel.vue file closes and I can not do anything with it. 

I have tried:

• Invalidate caches & Restart
• Remove .idea folder
• restarted computer
• checked if file works normally in git client
• tried to create file with the same name in other project (also does not work) and I have also tried to rename it there and then it works
