Log file spammed and filling disk

[sterling]

"OpenSSH for Windows" version
0.0.10.0

OS details
Windows 10 Pro

What is failing
sshd.log file is being spammed and growing very quickly. The log file easily grew to 75GB before I realized what was filling up my disk. I can successfully ssh into my Windows machine, which is why I never suspected any issues with OpenSSH until I found the massive log file.

Expected output
No continual spam in logs

Actual output
Turning on the sshd service for about 1 second resulted in a 16MB file with the same errors over and over again. Here is the beginning of the file (full log attached):
