Kosmobits_pins.h no such file or directory even thogh its there

So I was working on an arduino code gamer I was in project 19
So I put all the code but it told me KosmoBits_pins.h no such file or directory so I searched onnline and they said to download libraries so I did it still the same error until I watched some youtube videos and they said to check your libraries so I did and I found the files (i did check the spelling and capitalization I even opened the project from the library ) so please some help thanks
Btw the ide version is 1.8.9 and the board I'm using is a genuine uno
There are some pics

Not enough information. If you will provide more details, I’m sure we can help you out.

For now, all I can tell you is that if you install a library correctly, and have the filename right, you won’t get that error.

Posting tips.

  • Always list the version of the IDE you are using and the board version if applicable.
  • Remember to mention the actual board you are using.
  • How to insert an image into your post. ( Thanks Robin2 )
  • Add your sketch where applicable but please use CODE TAGS ( </> )
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Guessing is not the best way to describe an issue. Actual facts are the most important.
  • Remember that the people trying to help cannot see your problem so give as much information as you can
