New snapshots not working

[gyraether]

Can't play instances past 26.1 snapshot 1--can create them but the error message below comes up when trying to load it. Have tried reinstalling in case the issue's on my end but didn't seem to resolve it.

Hi! I've investigated the crash with Minecraft 26.1 snapshots (Issue #458).
It turns out daedalus was missing support for Java 25 (JavaRuntimeEpsilon) and the new default-user-jvm argument type.

I've submitted a PR to daedalus to fix this:
gorilla-devs/daedalus#20
Note: Since GDLauncher's Cargo.toml is currently pinning an older version of daedalus, you'll need to update the dependency to pull in these changes once the PR is merged.
I've confirmed that these changes fix the crash!
