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.

Comienza reproduciendo el comportamiento informado con la comprobación de actualizaciones de la aplicación, tanto mientras se realiza otra acción como cuando está in reposo. Usa la captura de pantalla adjunta y el error resultante como punto de partida de la investigación; el trabajo estará terminado cuando la comprobación de actualizaciones ya no bloquee la aplicación ni produzca el error informado.
