Quoting [1] :

MTP device handling has been rewritten, which fixes an enormous amount of bugs
(Andreas Krutzler, KDE Applications 18.12.0)

So it is the real fix and not a workaround like changing the type of USB ports.

I read somewhere (blog probably) the root cause was that concurrent access to
MTP devices was broken : as soon as you would ask for 2 actions they would be
sent in parallel to the device instead of being serialized and break the MTP
connection. But I can’t find the source anymore.
