A350 installation issue

[ROSSI ERIC]

Hello, I have something strange happening, it looks like it started after a recent Steam update. I'm using MSFS 2020 and had only installed the A350-900 for the 2020 version, but the A350 for 2024 keeps installing itself automatically. When I delete it, the A350 no longer appears in the aircraft selection menu. On top of that, after uninstalling and reinstalling it, the electrical power only works every other time.
