Issue with Sample WPF Modification

[Mindset]

I get this message in my Output Tab when I load and unload the indicator

Error during cleanup: Object reference not set to an instance of an object.
Error restoring chart layout: Object reference not set to an instance of an object.
Error during cleanup: Object reference not set to an instance of an object.
State.Terminated: Restoring original content...
Restore: Error restoring layout: Object reference not set to an instance of an object.

Its a new message and it doesn't come up in my control center log - never seen it before.

Hello Mindset,

I am not able to reproduce.

You might have an older version.

Ensure you are updated to 8.1.4.2 before continuing.

Then re-download this directly from the Desktop SDK and re-import it, then restart NinjaTrader.

I have done all that and even repaired the new install - still get the message!

Hello Mindset,

I don't think it is an issue with the script.

Below is a link to a video of testing it.

Try renaming the NinjaTrader 8 folder in documents and then run the repair again to create a clean installation environment.

Ok so I have done a clean install - no scripts and the error message disappeared . hallelujah.
10 minutes in and I get this message

04/04/25 11:40:45	Connection	Simulated Data Feed: Error in opening connection Simulated Data Feed, exception caught: One or more errors occurred. (Panic)

Tried reparing to no avail.
Again, in 14 years never had this message either - is there some issue with the latest version of NT8?
I feel like I am fighting with NinjaTrader Software at the moment.
Edit - MyLive connection still works however, but I cannot download any historical data FYI
I should also add my Automatic Range vs fixed range doesn't work either.

Scrub that - LIve feed and Kinetick endofday now reporting the same issue.

Hello Mindset,

This would be an unexpected error from the simulated data feed.
