It's not that things break when upgrading, it's that we need to call a halt to new feature development and go upgrade all lambda runtimes before the deadline because AWS won't support deploying lambdas running deprecated .NET Core versions. In the last couple years we've had to stop everything to make sure all of our 2.x code was up to 3.1 (6 wasn't out quite yet) and a year alter we moved everything up to net6 to stay within the AWS deployment support.
