TL;DR: Technical viable but I think it doesn't bring enough benefits in enough situations to be a success in most areas of the world.
Yes, but uh risky.
Close to where I live are old end/post WW2 above ground large aircraft hangars you can buy/rent etc.
So there had been airship startups, multiple times.
I'm not sure if a single of them is still around.
The main problem isn't a stable hull, or non explosive gas anymore.
AFIK:
The main problem is that there are nearly always much much more convenient solutions.
Like they only make sense (due to economics,convenience) for transporting things which don't fit easily on the road, e.g. huge thing. Which also tend to be heavy so the airship need to be huge.
But airships are sensitive to wind and the bigger the more wind can get a grip on them.
And only being able to use them at top (wind) wetter conditions where plains, trains and cars can go even with pretty bad wetter is a major problem.
Another use-case could be areas where cars can't go, but airships can e.g. huge swamps, areas with a lot of folding, but likely not mountain sides where there is no street be you need to transport things, too. But how common is that and how many of that cases could also be fulfilled with other "special" but more convenient to use transports like larger drones.
