Describe the issue
What exactly is telling you that the mod is incompatible? all I know is when I added the mod to my modpack it started crashing if I removed it it would work as normal.

Game Log
Please always include your .minecraft/logs/latest.log file right after the issue happened.
Please don't send the whole log as plain text here. Upload the file to https/gist.github.com and send the link.
link is here lmk if you need more logs
Screenshots
If screenshots would help to explain the issue, please include these.

Basic Informations (please complete the following information):

• OS: Windows
• FancyMenu Version 3.1.5
• Forge/Fabric Version forge 47.2.0
• Minecraft Version [e.g. 1.15.1]
• Active Mods mod list is way to big so if you want to see the list its in the latest.log

I don't see why this should be related to FancyMenu. It crashes because the local player is accessed too early.
Did you open a specific screen or something right before it crashed?
