[Windows] All OH logs stop when Jython is in the classpath

Put this in a script and post the result…

import sys
from org.slf4j import Logger, LoggerFactory

LOG = LoggerFactory.getLogger("jsr223.jython.TEST")
LOG.warn("sys.path = {}".format(sys.path))

It sounds to me like your python.path may not be set. It would also be interesting to have you test the bundle…
