Invalid XML Format after update

Hello all,

I updated my Portfolio Performance app today and when I tried to start it again it won’t start.
I get an error message saying: (see pic)

Any idea how I can fix it?
Im running macOS Big Sur 11.6.3

Any help appreciated!
Thank you,

Check your Java version. It should be 11, not 17.

Thank you for your reply.
I am running Java 14.0.1

I found the problem though.
The xml file wasn’t saved properly when I closed the application for the update, it was missing a whole chunk at the end with the “name.abuchen.portfolio.ui.views.SecuritiesTable” etc.
Managed to restore it from the backup.
