Panic in window resume unwrap assuming a monitor exists

[matthiasbeyer]

dioxus/packages/desktop/src/app.rs

Line 451 in 95cde59

let monitor = window.current_monitor().unwrap();

This line unwraps a None for me with the generated code from dx init.
I do not get a windows showing anything, but I have to Ctrl-C me out of there and then I get the output. With RUST_BACKTRACE=1 I get:
