[FEAT]: Add Try catch to make open files without icon do not crash

[chaozwn]

Requirements

• This feature isn't just a vague idea and can have a good practical solution.
• I'm completely sure that this feature fits into this plugin.
• I'm willing to implement this through a PR.

Problem

When opening a file without exclude_filetypes, it will crash directly. It is recommended not to do so, and it is not displayed by default.
