I have same error("Unable to connect Last.fm - if you have a firewall the proxy settings need to be configured in Preferences/ Internet") and error log doesn't have much info
I'm running this on wine-staging 8.8
Host OS is Endeavour(Arch)
Tried to setup multiple prefixes in 32 and 64 bit, also tried the TLS 1.3 enabling steps but it didn't work either. I also tried previous release and overwriting v3.5 release with the patch you provided above.
And I do not see this error : "Last.fm login error: The request was aborted: Could not create SSL/TLS secure channel." which sacrebisous got.
MusicBee itself works great, only lastfm logging isn't working. If there's any other way to enable that like using 3rd party tool/cli script I'm fine with that too.
