You have duplicate plugins in d:/RabbitMQ/RABBIT~1/plugins/.

Removing the 3.6.10 versions should help.

One module cannot invoke a function that comes from rabbit-common.ez:

https://github.com/rabbitmq/rabbitmq-common/blob/stable/src/vm_memory_monitor.erl#L130

Something is broken in that node's library directory (having two sets of plugins

suggested as much).

At this point I'd stop the node, back up the data directory, re-install from scratch and

replace data directory with the backup.
