When you used the File System Repair tool on your storage, and check it all, does it gave you "successful" or does it gave you some issues to be fixed?
If there are some issues, then it must be fixed first, and you can install a new installation on a new USB stick to run the DSSv6 and then go to console mode to run FS repair tool again.
Also if the new installed DSSv6 on a new USB stick runs fine, that means the issue is related to the USB stick that you currently have. And you may need to re-install DSSv6 on it. ( for your settings/configurations, if you already saved them, then you can apply your saved settings to the new installed DSSv6, and if you don't have saved settings, please open a support ticket, and send us a system logs file ( even if it's old ) for your system, and we will try to get your settings/configurations and support you with them ( if that possible for your case) ).
Please note that by using the latest builds of DSSv6 now, it is recommended to update your Controller Firmware, so please check your controller website and get the latest firmware for your controller and update it.
