[BUG] Sometimes blocks will run indefinitely without any error and must be manually stopped

Mage version

0.9.70

Describe the bug

Frequently while developing and testing pipelines, I run into an issue where when I execute a block, it just runs indefinitely. For example, the image below shows a data loader with only a print statement and it never finishes or outputs anything. The container logs show that the block was started, but nothing beyond that. Sometimes reloading the page helps, sometimes it doesn't

To reproduce

This happens sporadically. Seems to happen more often after previous errors have occurred.

Expected behavior

Block to successfully execute.
