Make a test with another Launcher like MultiMC or AT Launcher: Create a Forge 1.20.1 profile (forge-47.4.0) and start it once - close it in main menu Then copy the mods from the curseforge mods folder to the new launchers mods folder and test it again

Update your AMD/ATI drivers - get the drivers from their website - do not update via system

There are no issues - what exactly is not working? Does the server crash or is it unjoinable? If you refer to the red error blocks, these can be ignored - these are common recipe and loot_table error - mods are overwriting these

Remove mods one by one or in groups until you find the mod causing this issue

This is a warning and can be ignored - add the new crash or log

Also make a test without Repurposed Structures and/or IDAS (Integrated Dungeons and Structures)

Is there a change without the mod tacz?

Do you place this one in a specific biome related to yungscavebiomes? Make a test without yungscavebiomes

Then it is another mod - I have no idea - maybe a biome related one or similar
