Data Guard Issue

We have two Oracle 19c databases set up in a data guard configuration. One is the primary and the other is a physical standby. I was trying to do a schema refresh by copying the schema from another database. The physical standby ran out of disk space. The sys admins had trouble adding space and it took too long. Now I can't get the two databases synced. The errors are:
ORA-16853: apply lag has exceeded specified threshold<http://www.oracle.com/pls/db112/error_search?search=ORA-16853> ORA-16855: transport lag has exceeded specified threshold<http://www.oracle.com/pls/db112/error_search?search=ORA-16855> ORA-16857: member disconnected from redo source for longer than specified threshold<http://www.oracle.com/pls/db112/error_search?search=ORA-16857>
That status shows that the current log on the primary is 64576. The last received log is 64569 and the last applied log is 64345. Those numbers haven't changed in over an hour.
If anyone has any idea of how to fix this, other than dropping the standby and rebuilding the data guard from scratch (which is where I'm headed), I'd appreciate it.
Thank you,
