The 2023 mini banking crisis has its own wiki page and it's quite informative. Of the three banks involved, one bank saw its shares drop 97%, another "shareholders lost all invested funds" and the third got auctioned off for pennies on the dollar. No investors were bailed out.

Banks go bankrupt all the time. Community Bank and Trust of West Georgia went bankrupt just 3 days ago. The Metropolitan Capital Bank & Trust that went bankrupt back in January. 99% of the time the investors are completely wiped out. Bailouts almost never happen, which is precisely why it's such big news when it happens.
