Exact steps for others to reproduce the error

  1. Applied Quick Smoke on Default Cube

And By "2.83.3LTS Doesn't Blast Off" I Mean It Literally Doesn't Blast of Even after Thousands 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
