My mod list (if is an incopatibility problem): https://pastebin.com/Bh7k9873

Ps: the screenshot was made before I remove "Giselbaer's Durability Viewer" mod, even without it the position is wrong

There's pretty much no way that I'd be able to tell what's causing it to happen without downloading all of the mods you have installed and removing them one by one. It's likely due to some other mod either replacing or moving where effects are being rendered, so that mod would likely have to implement this mod's API rather than the other way around. If you do find the problematic mod, let me know and I'll look into it.

Whenever BedrockIfy is installed, I experience this issue.
Thankfully, the mod lets you straight up disable some of its mixins. After some testing, I found that disabling "client.features.screenSafeArea" allows the status effects gui to be moved.
