Binaries for Official Monero v0.18.3.2 are now available at http://www.getmonero.org
Also Feather wallet: Go to help -> Check for updates
Update your wallets! This has the fee fix!
I fixed an issue that could cause this. Let me know if you still encounter this after the upcoming release.
It looks like the close issue is still there, here is what I am seeing in the command line after I close the app (feather-2.6.5)
