Will downgrading MacOS to Big Sur cause failure to open

Well, Sonoma has really messed everythinng up with after effects and my plugins. I have plugins I can't upgrade to th enewest version without paying for it again. And the ones I use the most don't work anymore with sonoma and after effects 24 only woks with sonoma now, it sucks. Should I downgrade to big sur or ventura? will it even work?
