Claro. Antes de reiniciar, guarda el proyecto para no perder cambios:
Cómo guardar tu trabajo en Flux
  • Flux guarda automáticamente muy a menudo, pero es buena idea forzar un guardado:
    1. Revisa la barra superior: si ves un indicador de “Saving/Saved”, espera a que cambie a “Saved”.
    2. Cambia de pestaña entre Esquemático y PCB y vuelve: esto suele disparar un guardado.
    3. Edita una propiedad del proyecto (por ejemplo, la descripción) y vuelve a su valor original: forzará “Saved”.
    4. Si tu navegador muestra “Are you sure you want to leave?”, elige permanecer hasta ver “Saved”.
Copia de seguridad rápida (por si acaso)
  • Duplica el proyecto: en el menú del proyecto (arriba a la izquierda), usa “Duplicate/Make a copy” si está disponible en tu plan.
  • Exporta la BOM o toma capturas de pantalla clave (posición de componentes, propiedades), por si necesitas referencia tras reiniciar.
Tras reiniciar el PC
  • Abre de nuevo Flux, verifica que el proyecto carga con estado “Saved”.
  • Prueba mover un solo componente:
    • Asegúrate de estar en PCB 2D.
    • Selecciónalo en Objects, desbloquéalo en Inspect (Locked → Unlocked).
    • Mantén Shift y arrastra sobre el footprint; rota con R si ayuda.
Si el problema persiste después del reinicio
  • Prueba otro navegador (Chrome/Edge actualizados) o ventana de incógnito (para descartar extensiones).
  • Limpia caché del navegador.
  • Verifica que no esté activado ningún filtro de selección o herramienta de pan persistente (pulsa Esc para volver a selección).
  • Dime exactamente qué componente estás intentando mover (por ejemplo J1, U2) y si el candado aparece en el Inspect, y lo resolvemos paso a paso.

@copilot what other components am I missing in my project?

The following components are needed for your audio amplifier project:
  1. Audio Input: You'll need a 3.5mm Audio Jack for line input and a Bluetooth 5.0 module for wireless audio input.
  2. Power Supply: You need a power supply unit. Since your operating voltage is 12V, you can use a DC power supply that provides the required voltage and current.
  3. Volume Control: A potentiometer can be used to control the volume.
  4. Output: To send the amplified signal to speakers, you'll need screw terminals. Additionally, we suggest using a protection circuit for the speakers.
  5. Indicator: You specified the use of an LED in your design. This can be used to indicate power on/off status, or Bluetooth pairing status.
  6. Filter: It would be good to have an audio filter to eliminate unwanted frequencies and noise.
Please note that the specific components you select will have to maintain a THD (Total Harmonic Distortion) of less than 0.1% at full power, have a frequency response between 20Hz to 20kHz, and operate between -40 ºC to 85ºC as these are your project requirements.
Please make sure to select the components which are RoHS, FCC, and CE compliant.
You also need to ensure that the selected Class D amplifier can deliver the required output power for your project, which is not specified in the project description.

@copilot can you recommend an audio amplifier for my project?

copilot

Your project criteria suggest you are looking for a Class D audio amplifier with a frequency response from 20Hz to 20kHz and a total harmonic distortion (THD) of less than 0.1% at full power. The TPA3116D2 by Texas Instruments would be a suitable fit for your project. It has a bandwidth of 20Hz to 20kHz, and it provides a class D operation with high efficiency and low distortion.
Moreover, it has an excellent thermal performance, operating from -40 ºC to 85ºC, which matches your project requirement. The TPA3116D2 can deliver up to 100W into a 2Ω load and 50W into a 4Ω load from a 12V supply, which should be more than sufficient for a stereo setup, considering that your project requires two channels.
Don't forget to consider other components that you might require, such as Bluetooth modules for connectivity, 3.5mm Jack for audio input, LED for user interface, and power supply components considering your operating voltage is 12V.
Please remember the above recommendation is based on the project description provided, for detailed design and connection of components, a design schematic will be needed.
