Error while saving exported settings json file (replace with existing)

[TheHasagi]

If you try to export the settings with the same as existing one it should ask you to replace the item or no, actually it saves the file with (1).json format, but shows an error message (see the screenshot)

Steps to reproduce

1. Open Adguard - settings - general - export settings - save the file with a name a.json
2. Go back to general - export settings - try to save the file with name a.json - tapn to save

Expected behavior

It should ask you to replace the file with an existing name

Actual behavior

It saves the file (actually), but shows an error (that’s incorrect)
