Runs but stops suddenly

[falconv05]

I was running https://colab.research.google.com/drive/15_sd1tymWK-HPK88iWb12AP8j0U8hZXG
By adding the torchmetrics part in step 2.
But since this week I have not been able to use it because it immediately stops after step 3 shows "startup complete". Sometimes I am able to generate 1 single image and then step 3 stops running and turns red. Any idea what is happening?
