I'm still struggling to reproduce the issue. Trying on my own PC locally as well as on google colab yields nothing.

The fact that you do get tensorboard logs, but none of them are captured by ClearML means there might be something wrong with our tensorboard bindings, but it's hard to pinpoint exactly what if I can't get it to fail like yours 😅 Let me try and instal exactly your environment using your packages above. Which python version are you using?
