I have the same problem, mine is loading for couple of hours and showing some numbers. Check the screenshot:
BAS Issue.png
My version is : 27.8.1 downloaded yesterday on 27 Sep 24
I have a couple of projects that was set to do 500 activities, however they stop just after 100 for no reason, the system freeze. It is not a system resource issue, there are more than enough resources to conduct a couple of threads.
There is a variable set to let the system run to do the X amount of success and a X amount of fail, non of these have reached the desired amount.
