Dear @IntuitGabi 

2021 Lacerte allows log-in, displays itself intact and then slams shut closed.

This has happened multiples days in a row. And it occurs in waves. Windows Reliability Monitor tells me...

And then gives me these details which, if I could understand, I wouldn't be prepping tax returns.
