Podcasts will not delete then hangs MB

[PurpleHaze]

MB generated the error text shown below in Part A when I attempted to delete an established podcast. The dialogue said report it to you.

Additionally I have copied a set of errors from today's error log and shown in Part B after this.

The podcast url is http://www.bbc.co.uk/programmes/b00729d9 and importantly I have this configured in MB as 'Do not download' using the 'customise subscription rule'.

It would appear to be ignoring this and I can see that MB is downloading episodes which is probably the reason for the error, ie the podcast can't be deleted because it is actively downloading. Yet I have it set not to download. This is odd!

There is also something strange going on since I updated W10 to 1903 build 18362.175 on 13 June. Since then MB hangs frequently when trying to access anything on my WD EX2 Ultra NAS shares. It may eventually located the share but mostly I just get the spinning circle which I then force a close using task manager.

[Steven]

I am not able to reproduce the behaviour where the customised subscription rule is being ignored and do not see how it could happen from looking at the code.
As to the error itself, i think this should address the issue:
https://getmusicbee.com/patches/MusicBee33_Patched.zip
unzip and replace the existing musicbee files

Thanks Steven, that worked perfectly.
