Dotemu, the talented developers behind the acclaimed Streets of Rage 4, have announced this morning that they have deployed a new update which should resolve the issue of crashes when playing Streets of Rage 4’s Survival Mode on the Nintendo Switch family of systems. The issue arose when Dotemu released the previous update last month, which included a batch of content and fixes. Streets of Rage 4 is available right now on the Nintendo Switch Shop.
Survival Mode crashes in Streets of Rage 4 now fixed on Nintendo Switch

I didn’t experience any crashes when playing Survival Mode, but thankfully they fixed it for those who did.
I’m surprised they focused on the Switch version first, normally it’s the last to get any focus when it comes to fixes. Glad they are on top of it.
