TL;DR: you can subtly dispel magic. Whether or not that solves your bubble problem is a contested question.
Yes. Subtle Spell will allow you to cast even while "enbubbled."
Subtle Spell allows you to cast a spell--at the cost of a sorcery point--without providing the somatic (gesture) and verbal component(s) of the spell.
Since you don't need to provide the verbal component, the bubbles don't interfere with your provision of that component, and you're good to go. As long as you've got sorcery points to spend.
Then maybe you could dispel magic the effect (via Subtle Spell) to be free of the bubbles.
As the accepted answer attests, you can dispel the pink bubble effect. And as dispel magic itself has a verbal component, you of course need to Subtly cast it (as above).
However, this later answer makes what I think is a good argument--supported by Sage Advice--that dispel magic will not remove the pink bubble effect.
