Ckan: Problems opening CKAN on MacOS maybe related to GUIConfig.xml

[MaltYebisu]

Background

CKAN Version:
CKAN version v1.25.4+7413c232f2ff

KSP Version:
KSP 1.6.1

Operating System:
MacOS 10.14.2 (18C54)
Mono JIT compiler version 5.18.0.225

Have you made any manual changes to your GameData folder (i.e., not via CKAN)?
No

Problem

What steps did you take in CKAN?
Fresh install of KSP 1.6.1 with ckan.exe in the folder.

Ran mono --arch=32 ckan.exe in terminal

Quit CKAN

Ran mono --arch=32 ckan.exe in terminal again

What did you expect to happen?
CKAN to open both times

What happened instead?
The first time CKAN opens like normal (I can install mods etc)
The second time CKAN stop responding before it loads

If I delete GUIConfig.xml from the CKAN folder then CKAN starts normally again

CKAN relevant files:
The CKAN folder created in the KSP directory:
CKAN folder.zip

The output in my terminal window:
Terminal output.txt

The stack trace seems like it's a duplicate of #2595, which is fixed in #2600, but not released yet.
There's a test build in #2595 if you want to use the GUI until a new CKAN release, else I think the problem is not existing in the consoleUI nor with the normal command line interface, so you could use them.

Thank you. It looks like the same bug. ConsoleUI and command line interface works fine.

Sorry for reporting a duplicate issue.
