I also want to report that my game is crashing in nearly every fight now.
I'm on Switch Lite. Have been playing fine for around 20 hours until updating to the most recent patch. I'm in Act 2 and the game crashes in nearly every battle. Clearing Cache, reinstalling etc. did not work.
There might be a correlation I've noticed that it crashes when big explosions happen on screen but I've also noticed crashes in regular battle activity.
I think the patch should be reverted. The game is unplayable for me currently.
I play on the original Nintendo Switch, and before the update, no matter how much stuff was happening on the screen, the game didn't crash....but instead dropped frames massively. The game rarely crashed in battle, and crashed just a few times outside of battle, that is, until ACT IV (be wary), where the game started crashing
while SAVING around 65%~70% of the time, which pretty much caused me to stop playing because whatever accomplishments I made before attempting to save would be lost (not saved). I've already submitted my Nintendo Switch cloud save file to the developers; now that this new update is out, hopefully, they can finally delve into our crashes.
Now with this new update, I can only imagine how terrible it would run if I boot up the game again...so that'd be frequent crashes in battle on top of crashing during the saving/auto-saving process, which equates to an absolutely unplayable game. Technically speaking, I can only suspect that there are some nasty memory leaks and/or multi-threading tasks that get bogged up which causes the software to crash on the Nintendo Switch.
I wish the development team the best of luck in releasing a performance patch for the Nintendo Switch version soon.
