I still am crashing upon various commands. This has been happening since 3/18/2021.  This is not good.  I have tried everything suggested and nothing works. Considering switching vendors at this point, even though that  will be a nightmare too..  

How do I uninstall and reinstall the program? Will my data files be lost if I do this? Lots of returns in progress or  waiting to be filed. 

please help.
