My Home Assistant version: 2025.1.0b0

What I am doing:
just using HA

What I expected to happen:
Browser-mod side panel to be usable

What happened instead:
It's a blank screen with an error in the console

Minimal steps to reproduce:
Upgrade to HA 2025.1.*

Error messages from the browser console:

By replacing the space in the checkboxes ([ ]) with an X below, I indicate that I:

• Understand that this is a channel for reporting bugs, not a support forum (https://community.home-assistant.io/).

• Have made sure I am using the latest version of the plugin.

• Have followed the troubleshooting steps of the "Common Problems" section of https://github.com/thomasloven/hass-config/wiki/Lovelace-Plugins.

• Understand that leaving one or more boxes unticked or failure to follow the template above may increase the time required to handle my bug-report, or cause it to be closed without further action.
