The session is active, but there is no way to retrieve data from the session.

I lost 4 working days and 500+ CU on retraining models, because... The session is active, but there is no way to retrieve data from the session.
What should I do? I’m thinking of switching to other services, yours is ruining the delivery process

Additional context
Link to a minimal, public, self-contained notebook that reproduces this issue.

• Share the file using your GitHub account using File > Save a copy as a GitHub Gist.
• or Share Drive notebooks using the Share button then 'Get Shareable Link'.

I'm not sure I follow - to save data you can try frequent checkpointing out to an external service (Drive for instance) as the notebook will terminate when it's done executing and the runtime will be recycled.

Can you reliably reproduce a session that terminates unexpectedly?

[msasmsasmsas]

Hi,
Yes, this situation is reproducible.
Almost every time the connection to the notebook is lost, after that the session can be restored, but it is not possible to download anything or complete at least some line of code

[EvanWiederspan]

can you say more about "not possible to download anything or complete"? So you show as connected to a runtime, but it's not letting you execute code?
