I'm not on the beta, but I've reinstalled the sim a number of times, and every time I have to again disable items I don't want active, and enable items I do want that the sim doesn't recommend. And I recall one of the initial problems when I tried the TBM in 2024 was that it had no sound, and installing the 2020 version of the 930 is what sorted that out. I'm not sure if you've checked this, but I have a hunch that when you switched to the beta, the sim may have disabled your 930 from 2020, and enabled the 2024 version. And even though I'm not on the beta, something did change with my TBM about a week ago, I suddenly had problems starting it. As an experiment, I moved the 2020 Asobo model to my Community folder, and it fixed the problem. But now I wonder: did the 2024 version get enabled somehow? Maybe moving the 2020 version from the Official2020 folder to the Community folder just triggered it to swap the 2020 version in again.
What I would do to help diagnose the issue, is look in my aircraft list to see which 930 the sim was loading. It's possible it reverted to the 2024 version for some reason, and you didn't notice. If you haven't already tried this idea, it might be worth your time to check. The 2020 version will be listed as "Daher TBM 930 - Asobo Studio." The 2024 version will be "Daher TBM 930 - Asobo Studio" as well, but underneath it will say "Passengers." You could also check by searching "TBM" in marketplace->my library to see which one is enabled. The 2020 version is 0.1.120 and the current 2024 version (found in "base content") is 3.19.0 although 3.10.0 is also available for me.
Hope you figure it out, it's such a great plane to fly.
