'What does the yellow background on filename mean in Intellij?

I think it might have something to do with asynchronous tasks but I don't know for sure. Could someone please clarify this for me?

Also what do the yellow frames mean when you are debugging?

Solution 1:[1]

This color indicates the non-project files (libraries), you can customize it here:

non-project files

Make sure to restart the debugger for the changes to have effect.

If this suddenly happens to your project:
Consider closing pycharm and deleting the .idea/ folder of that project.

After reopening the project the project, pycharm will detect all files as normal. But you'll need to set up the project again. -> Set source-folder, add run configuration etc.

For me that was the faster solution than figuring out how to fix it.

One more mention: It happened after a merge which caused some version conflicts and required to "roll back" a file.

This also happened to me and the cause was that the project folder was removed from the 'project structure'. You can re-add it in Settings-> Project <...> -> Project Structure.

Settings-> Project <...> -> Project Structure.

The above solution did not work for me -- by happenstance, I was clicking around the settings in Intellij/GoLand and stumbled across a solution that worked for me.

When I went to the Project Structure, the Project Structure pane was empty and there was no way for me to manually re-add my project directory.

Fix that worked for me: Top Menu Bars -> File -> Repair IDE

A bubble window shows up on the bottom right, and I just clicked through the tooltips to repair different aspects of Intellij. In my case, the 'Reindex Project Structure" step worked for me (it was Step 3 of 6 in the repair process).

After repairing + waiting a bit for the project to reindex, everything went back to normal.
