Steps to reproduce

Updated to the latest version on my custom modpack and crashed with no crash report

I have tried to reproduce the problem with only or without "Inventory Profiles Next" and its dependencies installed.

• I have tested without 'Inventory Profiles Next' and its dependencies
• I have tested with only 'Inventory Profiles Next' and its dependencies and no other mods

I doubt this has anything to do with Polymorph.

This is a result of forge tooling sometimes not producing viable Jar files.

fixed with the release of 1.10.14
