Julia in Colab suddenly does not work

I had been using Julia in Colab for months, it had been working well until 8th Sep.

The template I use is:
Julia Template Colab

The installation (1st cell) suddenly cannot be complete. I tried to change runtime type, change versions, etc… something seemed working, but even after successfully run the first cell and refresh, Colab doesn’t recognize the Julia codes anymore.

Update: After having this issue for days, the template seems to work again (as of 12th Sep).
I notice that for the ones that don’t work, the Runtime shows “Julia 1.8.0”, while the one that works shows just “Julia”.
But I have no idea how to change the Runtime type and why it suddenly changed.
