During gameplay, the software completely crashes every hour or so and the standard Switch error message is shown. I have noticed that the crashes usually occur during an autosave.

There is a similar bug report (MCPE-45862), but that one is marked as resolved and there are still several people in the comments saying that they are still experiencing the issue. 

One difference between that issue and this one is that the person that wrote it was unable to access their world after several crashes, but I can still load mine just fine.

Additional details:

 - The world I use is a survival world created in version 1.11.0 (the game could crash in other worlds, but this is the only one I play on)

 - I am using some resource packs, but the crashes still happenned just as often before I started using them.

 - I am not using any behavior packs.

 - I have tried checking for corrupt data within the Switch's settings (which returned as a negative) and redownloading the game but that did not change anything.

 - I was able to upload the world to a realm, and then download it and play it on the Windows 10 edition; will test if the crash occurs on that later this week when I have time.

 - This is not an issue related to online gameplay as I always play with offline  singleplayer.

Edit- Tested the same world on Windows 10 Edition overnight, did not crash at all.
