Switch version keeps crashing

Hi,

I recently bought a Nintendo switch and a Switch Lite for my 2 boys. I bought them Minecraft for both consoles. It worked fine for the 1st week but now as soon as they try to load a world it says that software has been closed due to an error. This is happening on 2 different consoles with 2 different game cards. I have tried deleting all the data from switch memory restarting but still have the same issue. I have 2 very disappointed boys in my house at the moment. I have all the latest system updates done with both the devices and your Minecraft games. Please advise on what can be done to sort this.

Many thanks a very disappointed customer.
