That's not true. Season Two of Star Trek: Picard could not have been the worst season of Star Trek ever because it was neither Season Two of Star Trek: Enterprise nor Season Six or Seven of Star Trek: Voyager, nor was it Season One of Star Trek: The Next Generation.
PICARD season 2 is worse than TNG season 1 because at least TNG season was trying different things to see whst worked, and we got a few great episodes in that season, too. PIC season 2 doesn't have that excuse... they were going for an season arc and knew what they going for, and took such a nosedive after episode 2 that it took the finale to put things back into place and it still didn't fully stick the landing.
ENT season 2 was more boring than bad, though it meandered just as much as PIC sesson 2, so it can be equal to that season in that regard.
VGR season 6 was the most chaotic in terms of good and bad episodes, I can't even rate it because it seems so schizophrenic.
VGR season 7 was a lot of wasted time.
But... I will agree that PICARD season 2 is not the worst live action in the franchise. (I think I will say it's the next worst.)
That crown is worn by DISCO season 2. It was not only bad, but it was very chaotic and had a lot of meandering in the middle
and there were lots of boring parts within the season. It basically has the worst elements of each of the seasons I listed and condensed them into this single season. Truly, if Anson Mount was not there, I would have called that season an unmitigated disaster.
