Downloaded the latest version of chisels-and-bits-forge-20.1.20.jar and started the launcher but it exits with 'chisels-and-bits encountered an error during the common_setup event phase'.

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link here

Chisel and Bits is no mentioned there / not available

Did you try this build?

https://www.curseforge.com/minecraft/mc-mods/chisels-bits/files/7620767

There is an issues with moa_decor_cookery

Also add FramedBlocks:

Looks like one or more mods requiring it

Add the new crash-report if there are further issues

Thanks for the help. The issue seems to have been with the earlier version of Create, with the latest version Chisels and Bits does load. However, there is then a problem with me loading my saved world, I'm getting 'Errors in the currently selected data pack(s) prevented the world from loading.' I'm now trying to work out what might be causing that error. If I am creating a completely new world this does not happen.

With changing this version, the world contains stuff which does not exist in that mod build

You may have to remove these blocks via NBT Editor

The log or crash should be mentioned these

I've given up trying to get Chisels and Bits working, I've reverted to the older versions of Create, my world is too large and complex to try to fix things using NBT Editor. A shame as I used to use the 1.12 version of Chisels and Bits a lot. Thanks for your help.
