So mainly this option is for quick stacking methods. Not for studio stacking where lot of photos has to be taken? Or the insect will be knocked out completely if exposed for long in the gas chamber?

Keep in mind that there are some very fast stacking methods, especially methods that refocus camera lenses rather than moving a rail. 150 shots per minute are normal, and thousands per minute would be possible if there were a big enough buffer to store the files and a fast enough transfer speed to the place they are written. This works easily at up to 1x (or 2x with front or back converter) and higher m can be obtained by stacking or reversing lenses. Fast shallow high-m stacks can be done this way with microscope objectives on autofocus tube lenses.

This is true, even for amateurs.

I use DSLR Controller for stacking when I'm using my Tokina 100mm macro. When I was using flash, I had to add a delay between the exposures for fear that I'd cook my good Sigma flash.

I never tried to stack a live subject, but I'm confident that using the Alka Seltzer method, I could (with continuous lighting) get a useful stack before the subject became too active.

I made a fast 150 image stack of a live frog-mimic spider a few weeks ago, and I will post it on a new thread.

Here is the spider using fast in-camera stack generation:

I suspect this is not suitable for stacking, but for taking single pictures. By holding still, I don't mean they are motionless. The bugs I have done this to still move around. But they are not running or flying.

may be another source for CO2 are those small dust blaster guns feed by CO2 Cartridges availabele in the supermarket

I use them for cleaning my camera and lenses. I will try them on insects - thanks for that hint.

Rubbermaid makes containers with a separate "tray" inside that should work for this.
