Confirmed - I just tried updating and I am getting the same errors. I also tried cloning the repo instead of using the cargo.io release and the problem is still there.

A bad merge, perhaps?

I can reproduce this, but I'm not really sure why it would happen, it looks like it should be working 🤔
As a workaround, you can add the following to your cargo.toml:

profiling = { version = "1", features = ["type-check"], default-features = false }

@teddemunnik can you have a look at this?

To reproduce this, the following cargo.toml has this problem for me:

[package]
name = "egui_playground"
version = "0.1.0"
edition = "2021"

[dependencies]
eframe = "0.30.0"
egui = "0.30.0"

[lucasmerlin]

Ah, it's because profiling::function_scope was added in profiling 1.0.16 and egui only has a dependency on 1.0, so we should update the profiling dependency to be >=1.0.16

So the proper way to fix this in your project is to run cargo update profiling

[teddemunnik]

Ah my bad, sorry about that! Thank you for the quick fix @lucasmerlin

Probably epaint 0.30 should be yanked then and replaced with 0.30.1 that uses correct minimal version.
Or people like me would step on this rake again
