As you can see you have a problem with disk2, your 301GB partition. Unfortunately, you have not been able to get First Aid to work on that volume. So little is known about fixing an APFS partition or drive. Only Disk Utility from High Sierra seems to be able to deal with them. You could look through the available commands in the command line tool, diskutil. But from what little I know there is no fix for your problem except to reformat the partition and lose all your data.
