What is the expected behaviour/value?

When navigating to the page that shows saved builds I expect to not receive an error after a fresh install with no saved builds.

What is the actual behaviour/value?

When navigating to the page that shows saved builds I receive an error. I am given the option to dismiss the error or restart the application. Restarting the application just brings the error immediately back. Dismissing the error lets me create a new build. After creating and saving any build and navigating back to the saved builds page I am shown no saved builds and receive the error again.

How to reproduce the issue

Open POB or return to the select a saved build screen.

Character build code

I have no imported builds. I reinstalled windows to remove bloatware 2 months ago and POB was one of the first things I reinstalled. It worked fine after reinstalling it, but I was done with Sentinel league so I didn't try importing characters or anything. I opened it to update POB so I'd be ready for 3.19 and was met with the error.

Screenshots

Reproduce the problem by opening Path of Building with no saved builds and navigating to the saved-build selection screen. Start by tracing the OnFrame error from that screen and compare fresh-install behavior with the state after saving a build. Done means the screen opens without an error when no builds exist and continues to work after a build is saved.
