Had that happen with the engine too.
I created a topic over on the official Inibuilds forum. Would be great if those of you like @Jigsaw407 who have this issue can add any details:

Yes, 2020 liveries are no longer compatible with 2024 native aircraft. The AO/Roughness/Metal textures are using a new format, an Asobo only version of ktx2.
Not to mention the whole structure of 2024 aircraft is different from 2020. More modular now.
Added my 2cents at Inbuilds Forum on fuel issue. Still looking for cause.
They showed up with the older version of the T-33, but when I updated to the newer version (specifically for MSFS 2024) they vanished.
Okay, Inibuilds reports the problem is due to the more detailed engine simulation. As with a real first-generation turbojet, you have to advance the throttle slowly and steadily or the engine will stall out.
At first, even doing this, I was still getting stalls. Then I realized I had started the flight with the hardware throttle pushed forward to about 66% and then pulled it back rapidly, which to the sim looked like a quick shove forward at start and then fast reduction.
So next flight, I pulled the throttle all the way back before clicking fly, and then upon starting the flight, held the brakes and slowly and steadily advanced the throttle to full. Everything worked great! Engine stayed up, no stalls, flew a perfectly normal flight.
Well, until landing, when I realized I’d come in way too fast and bounced, so I instinctively slammed the throttle forward as I raised my gear to go around. And that stalled my engine.
But that was pilot error, not a problem with the sim. RIP Lt. Denny and his T-33.

Good to know it works - saw that post this morning. And nice to know it’s because it works the way the real one does. Well done Inibuilds. Off to fly.
