COVID response neither featured a UBI, nor saw everyone stop working (and the people who did stop working largely stopped working because of a combination of formal restrictions and voluntary behavior changes due to a contagious illness either banning their mode of business or resulting in them not having customers, additional government support, which was not structured as a UBI, was given because of that and to cushion the impact of it.)

15% unemployment is high, but it’s definitely not “everyone stopped working entirely.”
The CARES Act authorized a one-time payment of $1,200/$500 per adult/child in March 2020, an extension added $600/per in December.
The American Rescue Plan Act passed in February 2021 and added $1400/per.
This is the closest the US got to UBI-adjacent policies at the federal level.
It’s difficult to believe that the first payment caused a massive spike in unemployment, but the subsequent two did not.
I believe there might have been a slight confounding factor involved.
It has also been shown that people behave differently when they know the benefit will end.
Beyond these issues, for the COVID experiment there are far too many confounds to say anything conclusively about UBI from it.
Here in Europe, people moved to remote work, but nobody "stopped working".
None of that was universal, and none of that counts remotely as "income".
It's not clear at all from the pandemic what UBI would do, this is completely inverted...
Firstly, that's not at all true. Secondly, those who did stop working did so because they were unable to work, because their company could not operate without in-person contact (i.e., restaurants).
Also, the government benefits only came _after_ people had stopped working/companies shut down, not the other way around.
