Bug: MakeMKV can't handle moved/missing directories/drives

[fullmental]

Hi, I'd like to report a bug with MakeMKV. It seems that if you select a default drive or directory that ceases to exist, either from moving the folders or disconnecting the drive, MakeMKV stops working. It refuses to open a disc and it won't even open the settings menu. Each time you try, it will freeze up and crash with the following message:



The issue even persisted through a program uninstall/reinstall. I was only finally able to fix the issue by going into the registry and manually editing the MakeMKV entries for app_DestinationDir and path_DestDirMRU.

This seems like a mistake, the program should be able to gracefully detect if a folder is no longer available, or at the very least it should allow you to change the folder in the preferences menu without crashing or resorting to registry edits.

Any chance this can be improved upon?
