This crash occurs often during fuzzing. If you do not consider this to be a bug, please let me know and I can modify the fuzz target to handle this type of exception.

This is not an issue. SnakeYAML properly complains when a sequence is tagged with a scalar tag (!!str):

== Java Exception: java.lang.ClassCastException: class org.yaml.snakeyaml.nodes.SequenceNode cannot be cast to class org.yaml.snakeyaml.nodes.ScalarNode (org.yaml.snakeyaml.nodes.SequenceNode and org.yaml.snakeyaml.nodes.ScalarNode are in unnamed module of loader 'app')
