log from renoise, yabridge, wine

I'm trying to get d16's Punchbox VST2 running on Arch with wine-staging 6.19
(via the wine-ge-custom package).

All d16 plugins require you to go through an online login prompt through the
plugin before you can use it (even for demos) and after you successfully log
in, the plugin requires you to close it and restart it. The problem is, on the
next restart the plugin asks for the activation credentials again.

This problem is not limited to one DAW, Wine version, or plugin bridge it
seems. I have tested this with Renoise and Reaper as VST hosts, with Wine 6.14,
and with the yabridge and airwave plugin bridges. I am able to run other
Windows VSTs without issue.

The plugin works despite the UI being inaccessible - it responds to midi notes,
sounds like it should and and my DAW's VST controllers work (but i can't change
presets).

Attached the log from Renoise / Wine after I start the plugin, log in, close it
and reinitialize.
