bOS Client v 4.11.8 android/windows
Hello,
After updating bOS Clientt to version 4.11.8, I am seeing:

When i open it, it is empty (Events):

After pressing on "Events", I am getting an error:

There were no such errors on previous versions.
How can i slove this?
Thanks.

This has been already fixed in the latest release.
Edit: I just noticed that you already have the latest version. For me it works fine on 4.11.8, I know that this was a thing few versions back. Can you do a reinstall?
