Whenever I run any project, even empty ones, I get these 4 errors about input mapping. They are as follows:

`E 0:00:00:0053   parse_mapping: Invalid device mapping entry "x:" in mapping:

This only happens when I use the Steam version. Using the version downloaded from godotengine.org does not yield this error. I have tried rebooting and reinstalling Godot, neither of which have worked.

### Steps to reproduce

1. Install Godot from Steam
2. Create a new project
3. Run the project
