hotpatch fails

i am on debian using dioxus v0.7.10 with fullstack web project
when use `dx serve`
when i try `dx serve --hotpatch`
i get the following error:

> [dev] Build failed: Failed to emit module: failed to parse import section
> 1: failed to parse import section
> 2: exceptions proposal not enabled (at offset 0x34525)

Start by reproducing the failure in the Debian, Dioxus v0.7.10 fullstack web setup with `dx serve --hotpatch`, then compare it with `dx serve`. Trace the hotpatch build path from the `dx serve` CLI entry point and the reported import-section parsing error; done means hotpatch builds successfully without the exceptions-proposal error.
