Did you also upgrade mono to 4.4.2? Mono 4.4.1 and 4.4.2 both have a bug that causes that.

Thanks for the reply.

Yes, my mono version is 4.4.2.

So, nothing to do than wait for the next mono release?

Also, is the error important - does it keep Sonarr from working properly?

You could also downgrade to mono 4.2 if its available for your system.

It will cause issues, either getting queue/history from NZBGet or could also cause issues when sending an NZB to NZBGet.

I have downgraded mono to 4.2.4.4 for now, thanks.
