Description of issue: Sonarr has been running fine for a while, following a PC restart a “Epic Fail” error is displayed each time I try run the program. Message states: FileNotFoundException: Could not load file or assembly ‘System.Numerics, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies. The system cannot find the file specified.
I’ve attempted to uninstall and reinstall the application, however the same error is still displayed.
