Refresh stack on "Creating connection in model...", then Power BI is crashing.

[RadekG]

I have Power Bi report in which I am using a few tables from dataflow.

Today, I opened the report and adjusted PQ to use different dataflow (with adjusted tables).

After applying changes report stopped on “Creating connection in model..”, and then stopped responding and power bi closed itself.
I tried multiple times, I tried on different laptop and I failed to refresh the report.
What is interesting, copying whole PQ to separate/ new report works - all tables are refreshed after 5 minutes.
I need an advice what to try next. 😞

Hi, @RadekG 

Not sure what caused it, but for now, the known workaround is to recreate your dataflow.

If it occurs again,it is recommended to open a support ticket to let engineers look into the issue on your side.

Either exercise patience - eventually the meta data refresh (that's what is causing the delay) will complete - or if you're impatient do as you did - recreate it from scratch, with new, untainted meta data.

hahahaha, I could wait but refresh is crashing power bi.
What I am doing right now is:
1. I took the previous working version 
2. I am refreshing/ changing sources for each table (not in bulk), and refreshing them one by one.
