Same issue for me and same crash logs ...

same issue for me (1.19.4)

Same issue for me on 1.19.4, crash log here: https://pastebin.com/vdQEwxUK

Sorry everyone, it has been hard maintaining compatibility with Sodium.
What you are experiencing is an incompatibility between version 1.1.10 of Iceberg and Sodium version 0.4.10. Version 1.1.10 of Iceberg was designed for version 0.4.11 of Sodium, but that version has been removed.
I have now archived version 1.1.10 of Iceberg on Fabric, so if you are still on that version please downgrade to an older version to fix this.

yep exact same issue here... same error: https://hastebin.com/share/omuxojolow.yaml
