3.10 in tutorials didn't work owing to DT<DT_MIN

Hello, an error was reported when running the 3.10 in tutorials.“DT<DT_MIN. Recovery not possible!”. What could be the problem?
Here is the setting in Run, same as tutorials.

Tutorial 3.10 runs without errors for me.
In your screenshot, I see that “Time step factor” is set at 0.5, while the default value is 0.9. Did you change this setting? (It should not lead to divergence)

It’s possible that you made an error setting up the case. Please attach your project files (“Submit bug report”) so I can check. Or go through the settings carefully, comparing against the tutorial.
