Hydrogen stopped working

Two days ago it was all fine, then I started receiving errors like these:

internal error; reference = 6s9j9l8btaervc62u2rk1kto

I tried starting from scratch: npm create @shopify/hydrogen@latest, the mock store works. Created a new dev store and set up .env:

SESSION_SECRET="foobar"
PUBLIC_STOREFRONT_ID=<number>

PUBLIC_STORE_DOMAIN=<store-id>.myshopify.com

PUBLIC_STOREFRONT_API_TOKEN=<token>
PRIVATE_STOREFRONT_API_TOKEN=<token>

PUBLIC_CUSTOMER_ACCOUNT_API_CLIENT_ID=shp_<UUID>
PUBLIC_CUSTOMER_ACCOUNT_API_URL=https://<store-d>.myshopify.com/

Immediately same error.

So it’s not the config (it was working fine before, it’s not the store (doesn’t work with a brand new one). What else is left?

And why there isn’t a way to check these error ids?

SOLVED: Arch Linux update broke something. Now using Fedora 41 under Distrobox.
