I have a problem when i open the inventory it crashes the game i am using Feather Launcher and i have these mods can you help me fix this i have tried playing without the Inventory Profiles Next mod and it works fine not sure if its because of the mod or other mod because it was working just fine before this started happening from two weeks ago still can't fix it tried reinstalling minecraft and such

it will help you provide the logs from such crash

I can send the crash log here

the game crash one or there is a specific log file generated by the mod?

latest.log

so the crash is not caused by IPN.

I will advise you in future to do a simple test if you suspect that a mod causes a problem:
Remove the said mod and try the same action if it happens while the mod is missing that there is very high probability that the mod in question is not involved!

the crash is caused by incompatibility between sodium and iceberg
