Looks like a keyless chuck....maybe a strap wrench would help.

I tried with a strap wrench but to no avail

Pipe wrench is the next step. It will scratch the plastic, but so what.

Maybe something rigged like a breaker bar around a strap that you can add lots of length for leverage?

Most likely it's kind of hung up on a burr... I remember regularly using one that was at a job and just more leverage was the answer.

Otherwise I don't have any great ideas as I doubt this is a lubricant scenario.

Reading up on it there doesn’t seem to be a special trick, just push the spindle lock button and twist anti clockwise.
However, keyless chucks do sometimes bind and one trick is to tap the end of the drill bit sharply with a hammer. Obviously this might damage the end of the bit, so wear safety glasses.

Well, it will depend on what exactly is causing it to stick. Lubricant and then gently heating the chuck with a heat gun might help. As might tapping the chuck with a small hammer or wrench while you are applying leverage. Unless you don't mind losing the drill, I'd avoid going just a straight more force route.

It is semi-soldered to drill because of missuse. Bit probably were stuck in object while drill head still tried to spin it.

You will need to pull and easy hit bit from all sides, if it breaks just make sure it breaks so that it still sticks out.

And unscrew the head completely to give it room.

How does one do that?

If the chuck can open freely, then this is probably the solution. However, if the chuck is binding around the bit and can't open to give the bit room to release, doing this will just break the bit.
