Summary
When starting the server with the DivineMC-ab0f2e9 software (MC: 1.20.4) with the EconomyShopGUI plugin alongside MythicMobs, EconomyShopGUI does not load for unknown reasons. However, if I remove MythicMobs from the server, EconomyShopGUI loads correctly.
Steps to reproduce
Start the server with the EconomyShopGUI and MythicMobs plugins.
EconomyShopGUI will fail to load with the following error: https://pastebin.com/sn2p5AD9
Remove MythicMobs from the server and restart it.
EconomyShopGUI will start correctly.
Current behavior
EconomyShopGUI will fail to load when MythicMobs is present.
Intended correct behavior
EconomyShopGUI should load correctly.

Proposed fixes
The error could be related to the Adventure library. And I think the solution would be to add the library to the shaded version of the plugin.
