Answer 1

Based off of your pasting, as hard as that was to try to read, I believe your problem is that either you have a permissions issue or a directory/folder doesn't exist that Cassandra is trying to write to:

Failed to create log replica C:\apache-cassandra-3.11.5\data\data\system\local-7ad54392bcdd35a684174e047860b377/C:\apache-cassandra-3.11.5\data\data\system\local-7ad54392bcdd35a684174e047860b377\md_txn_flush_99189c20-ffd3-11e9-b69e-0752c2cde782.log org.apache.cassandra.io.FSReadError: java.io.IOException: Invalid folder descriptor trying to create log replica C:\apache-cassandra-3.11.5\data\data\system\local-7ad54392bcdd35a684174e047860b377 at

So you need to check out: C:\apache-cassandra-3.11.5\data\data\system\local-7ad54392bcdd35a684174e047860b377

See if that directory exists, and whether it is writable (not required to be Administrator or something in that nature). I'm not much of a "windows" guy, so the diagnosis of the issue will fall on your shoulders a bit.

Hope that helps to get things started.
