Installation of Sim Dispatcher in Xenbit Launcher

After installing the Xenbit Launcher and subsequently attempting to install Sim Dispatcher in that same launcher, I get the following error message:

Installation failed: the type initializer for “system.text.json.jsonserializer” threw an exception

Does anyone know what causes this and how to fix this error?

Thank you very much!

The following clients can now also be used. They do not require the XENBIT Launcher and are also fully “updatable”. If a message appears after startup to download the launcher, simply click on “Continue in the web version”.

Windows (x64): https://dl.xenbit.app/sim-dispatcher/SIM-Dispatcher-Setup-1.1.6-x64.exe
Windows (ARM): https://dl.xenbit.app/sim-dispatcher/SIM-Dispatcher-Setup-1.1.6-arm64.exe
Mac (Intel): https://dl.xenbit.app/sim-dispatcher/SIM-Dispatcher-1.1.6-x64.dmg
Mac (ARM): https://dl.xenbit.app/sim-dispatcher/SIM-Dispatcher-1.1.6-arm64.dmg

Of course, we are working on the actual issue.

Update: The issue has been fixed.
