ASM instance failed to start with the error (ORA-03113: end-of-file on communication channel) in a 6-node cluster

Tried sqlplus or srvctl, both fail with these errors.

Only core dumps get generated under the asm_home/db directories.
Additional information
* The issue was discovered after node evictions (separate issue).
* There are still 2 ASM instances running.
* The Oracle Clusterware / CRS is up and running on all nodes.
* Nothing gets writen to the ASM alert logs, nor any trace files get generated
