Bot Emulator does not show error message when it fails to load .bot file

[Kaiqb]

Version

4.2.0

Describe the bug

If .bot file is not valid, emulator does nothing. No warnings/errors.

To Reproduce

If the bot file has a missing comma or other errors, the emulator should show a message indicating that it couldn't load the file because the file was invalid. Instead, it just doesn't open the file.

Expected behavior

Show an error message to the users so that they don't try to open the same file again and again.
