We also use the same platform with similar results. It is somewhat comforting to know that we are not alone with this issue. The crashes seem to occur almost exclusively within the query builder environment, and don’t seem to follow any predictable pattern. Sometimes I am just scrolling through tables and clicking on them to see the column names.
The crash and restart process can be very frustrating - I have learned to save the query after most every significant step, but I still lose time and need to recreate query revisions.
I have often wondered if there is some kind of connection interruption that is causing the crashes, as what seems to cause a crash one day will work just fine the next thus making the issue very hard to diagnose.
The good news is that once the query is correctly built, it tends to work with no issues, and the automation features are incredible - having saved us a great deal of time.
Perhaps with several of us having the same crashing issue, a solution can be discovered and implemented.
