Why didn't my noivern's Boomburst attack hit this galarian weezing?

I was playing sword (after beating Leon) and went into the slumbering weald then crashed into a galarian weezing with the ability neutralising gas. I sent out noivern and had it use Boomburst on the weezing but it had no effect. As galarian weezing is poison/fairy type I have no idea how this happened, can you enlighten me? My noivern wasn’t under the effects of any status moves or those of throat chop, also it happened twice.

Let’s see… So, no ability Galarian Weezing can have can make Boomburst fail. Neutralizing Gas nullifies any abilities in battle. Now, onto Weezing’s moveset. Being a wild Pokémon it has to have Toxic, Belch, Self-Destruct and Sludge Bomb. None of these moves can cause Boomburst to fail. Now, we have determined that nothing Weezing can do can make Boombust fail. Now, this leaves a few options I can think of.

These are the reasons I can think of that are plausible. Hopefully this helps. Please comment if you find any other reasons. Other than this, it could be a glitch or a result of using 3rd Party software. I am not an expert on that, but it could be. If it is a glitch, it is currently not documented anywhere.
