Small timestep induces instability in flip simulation
Is that normal for FLIP to explode like this? What mistake in implementation might cause this? My understanding is that with more substeps FLIP updates accumulate more and more velocity, while PIC keeps getting new velocity from grid every substep, but i am unsure of how to fix it.

How to stop fluid simulation from exploding?
If all else fails, you may want to consider a premium addon like FLIP Fluids, which in my experience feels more stable than the default fluid sim, though it may be a bit costly. Consider trying the demo.

Fluid Simulation Failing to Complete Render
For troubleshooting conflicts between addons, it can help to test in a fresh Blender environment with default settings and installing/enabling addons one at a time. In case it helps, we have some instructions here for how to backup user-preferences, test in a clean environment, and then restore your original addons and settings: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Baking-Crash-Troubleshooting#testing-the-flip-fluids-addon-in-a-clean-installation-of-blender

FLIP-Fluids Compiled Addon!!! Works with Blender 3.4 :)
The above was built from the code on the GitHub repository, which is under the GNU General Public License. This license allows for redistribution. Unfortunately, I do not have binaries for MacOS or Linux since I only use Windows. Also, note that the above download is for Blender 64-bit (which should be the default on the blender.org downloads page). The GitHub version doesn't have pre-made materials like the paid version on Blender Market. (Note: The demo file on GitHub has watermarks on the simulation. This is the full version of the addon, not to be confused with the demo.)

Flip Fluids ignoring obstacle
Make sure that your objects have correct manifold/closed/watertight geometry. See this topic for more info and how to verify geometry: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Manifold-Meshes
