Bug report

When trying to use Hyperion web interface, it crashes and shows the Hyperion logo overlay:

Inspecting the console shows the following error message:

ui_utils.js:1211 Uncaught TypeError: Cannot read properties of undefined (reading 'available')
    at getSystemInfo (ui_utils.js:1211:62)
    at eval (eval at globalEval (jquery.min.js:2:2538), <anonymous>:17:24)

Steps to reproduce

• Installed 2.0.12 version with HyperBian in a Raspberry Pi Zero W
• Configured USB Capture card to use 640x480 and decimation 8
• Configured LED Hardware to use a WLED controller using tpm2net (using 834 LEDs)
• Edit the LED Hardware configuration to correctly position the LEDs, and after saving I get in the crash screen. Any page reloads shows the same error
• If clearing browser cache and reloading, after next login web interface seems to work. Next time editing LED Hardware leads to the same crash

What is expected?

• Web interface working properly

What is actually happening?

• Web interface crashes
