Error on start up

Thank you for reporting an issue.

Before reporting a bug, please make sure that you are running the latest version.
You can get the latest version number from CHANGELOG.md

Please try to fill in as much of the template below as you're able.

• What happened?
  Getting an error after pob checks for updates, if i use it the moment it finishes checking it crashes, otherwise it only writes an error
• What were you trying to do?
  Nothing.
• What steps will reproduce the bug?
  Check for updates.
• Does it reproduce every time?
  If you do something(like allocating skills, creating items) while it checks it crashes pob, otherwise it only gives out an error
• Provide a build code:
  Always provide a build code that exhibits the bug you want to report, even if it is not specific to a particular build. This helps us greatly to reproduce bugs faster. Otherwise, we will have to ask you for the code first before investigating, which would delay any possible fixes.
• Screenshots:
  

If you receive an error or experience graphical bugs, include one or multiple screenshots. GIFs or short videos are also okay, if the bug cannot be displayed in a still image.

Beginne damit, das gemeldete Verhalten mit der Update-Prüfung der Anwendung zu reproduzieren, sowohl während eine andere Aktion ausgeführt wird als auch im Leerlauf. Verwende den angehängten Screenshot und den daraus resultierenden Fehler als Ausgangspunkt der Untersuchung; abgeschlossen ist die Arbeit, wenn die Update-Prüfung die Anwendung nicht mehr zum Absturz bringt und den gemeldeten Fehler nicht mehr erzeugt.
