signal already disposed with select

[blset]

singlestage-ui-c51a63433042ff62/70938d2/singlestage/src/reactive.rs:80:52, you tried to access a reactive value which was defined at /git/checkouts/singlestage-ui-c51a63433042ff62/70938d2/singlestage/src/reactive.rs:127:24, but it has already been disposed.

here is why I tried
it bugs after one or two changes of the select
