There was a massive drop in demand, globally, at the start of Covid. Demand roared back far faster than predicted, particularly in Asia, and production couldn't/didn't ramp up again quickly enough to keep pace. Things looked like stabilising until the Ukraine war. Russia is using energy as an economic weapon, and you can directly track the impact of Russian action in the European gas markets in particular.
You also need to recall that while domestic gas consumption (including gas for electricity generation) is significant it is far from the only use, even in the UK which is quite uniquely reliant on gas for heat (and is also quite unique in the energy inefficiency of our housing.)
Statistics on gas use for the last few years don't bear out your theory - even in locked down winter of 2020-21, with kids out of school and many workplaces closed for the majority of winter, the increase in domestic gas consumption was quite modest. And certainly not at the same levels of increase as we've seen in wholesale natural gas prices.
And that's in the UK, which is heavily reliant on gas for heat in particular but also for electricity generation (though the latter is slowly improving.)
