`Uncaught TypeError: callback is not a function` On clean Fresh init project

I've just initialised a new Fresh project with deno run -Ar jsr:@fresh/init . I have made no changes to the newly initialised project yet. upon running deno task dev I see the following output: 
VITE v7.1.5  ready in 1062 ms

These files seem to be core to Deno itself, they aren't included in my source as far as I can tell.

This maybe an outdated Deno cache, try this first inside the example app: 
deno install -r --allow-scripts
deno install -r --allow-scripts
Otherwise I use example Fresh apps constantly and they all work (until I break them on purpose). Also make sure you are on the latest Deno version, e.g. upgrade with: 
deno upgrade
deno upgrade

after running deno install -r --allow-scripts I get the same error: 
error: script 'postinstall' in '@tailwindcss/oxide@4.1.13' failed with exit code 1

This is a brand new installation of Deno 2.5.0 on Nobara Linux via the install script. I've also tried uninstalling and reinstalling via Nix and get the same result. 
Current Deno version: v2.5.0
Looking up stable version

Local deno version 2.5.0 is the most recent release

Looks like switching to the canary build with: 
deno upgrade canary
deno upgrade canary
fixes this problem, see this comment -> https://github.com/denoland/fresh/issues/3432#issuecomment-3291250105

YES IT DOES! Thank you, just my luck to start working with a tool while there's a bug like this on the main release 😂
