Short description of error
2.90 Mantaflow Smoke Simulation with Turbulence Field Blasts Off after Frame 214. Didn't Blast off in 2.83.3 LTS. Nor in 2.82a Last Version
NOTE:- 2.83.0 Used to get Blasted Off as seen in this comparison 2.82 vs 2.83 Mantaflow Comparison - 2m05s

Exact steps for others to reproduce the error

Applied Quick Smoke on Default Cube
Added a Turbulance Field
These Steps were separately Done for Each Files
Changed the Buoyancy Density to 4 and Heat to 5 ONLY in 2.90 Blender FIle

And By "2.83.3LTS Doesn't Blast Off"I Mean It Literally Doesn't Blast of Even afterThousands of Frames! Here Goes a 60fps 1000 Frame SIM:-

Hello, first time commenting here and I also experienced something similar. I have been trying to create a fire/smoke sim and it always ends up with it "blasting off"

I'm using an Rx 5700XT with Blender v2.83.3, baked it with 200 resolution. There was also a turbulence field present in my scene
