What you did
According to the docs at https://github.com/bevyengine/bevy/blob/bd0c74644fda1c6cbdd2524c2920e81fce063648/crates/bevy_asset/src/server/mod.rs#L423C1-L425C21, we're supposed to be dropping the infos guard. However this is no longer true after #15509.
We should either pass the mutex guard to this function, or drop the guard before the function call.
