Hyperparameter Tuning- Ray Tune dashboard not working (transformers v4.9.2)

The Tune & Ray Config tabs on the dashboard do not work (anymore).
I upgraded the transformers library to latest version 4.9.2 to fix this issue however it seems to have broken the dashboard partly.
I was able to see the trials and results earlier and have not changed anything from my end.

I get the following error (see image).

The config tab throws an error - Invalid config, could not load YAML

Thanks for your help!
