Basic Informations (please complete the following information):

• OS: Windows
• FancyMenu Version: 3.2.3
• Forge/Fabric Version: Forge 40.2.21
• Minecraft Version1.18.2

Should be common sense not to anchor 2 elements to each other anyway.

I did once lose a lotta progress to this crash during a session of making the web in minecraft (basically remaking chromium but just image and text files stored on github servers lmao) + a few other less severe times.
