Turbotax 2021 Will Not Open

I purchased Turbotax Premier 2021 e download from Costco.  MacOS Big Sur 13.6, newer Macbook pro.  Installed the software fine first use, logged in, started return and saved progress.  I went in this morning to try to open the program and work on it again and it will not open.  Double-click on icon, goes to pop up where the program tries to do its update and then just closes.  I have deleted it, reinstalled it, restarted my laptop, same behavior.  I had this same exact issue with Turbotax last year, which support was not able to address.  I gave it a chance this year thinking surely they had figured this out by now.  I am a loyal Turbotax user.  I really do not want to go to a different program; however, I cannot go through this every tax season!
