Failed to load config
This issue can be displayed when you are using DarkBot v1.13.17 beta 98 or older.
There are two reason why this error appear. One of them is having Java 16/17 and second one is invalid path (Having bot in OneDrive directory or any other cloud disk)
Let's start from fixing our Java version. Navigate to Start > Settings > Apps > and search for "JAVA"
As you can see there are 3 Java versions, Java 8 Update 291, Java Se Development kit also 291 and Java SE Development Kit 17.
Now as we detected we have wrong Java version, simply click on it and then Uninstall.
