freezing when getting acknowledges after e-filing

[Hope]

After I efile a return and it is converted and transmitted the program freezes while getting acknowledges.  The only way to get out is to alt, ctrl and del.  Why?

I noticed mine sat for longer than normal and appeared to be frozen yesterday, but I just left it alone (I walked away so I didnt start clicking on stuff and make it worse) and it eventually finished.

I have the similar problem with ProSeries 2018 and 2019 in Jan. 2021. Every time I efiled a business client, the program stop working. I have to close it and reopen the program for efiling next client. This problem started three weeks ago or after installed ProSeries 2020 on my computer. I tried on another computer, it has the same problem. Contacted Intuit support but didn't solve the issue.
