After trying all the "solutions" listed in this forum (resolution change, scaling, etc., etc.), I booted my Acer Aspire running Win10 V(21h1) into safe mode with networking, ran TT and the activation screen actually appeared so that I could input my code!!!
This process of trial and error only took about 4 to 5 hours of my time!!!!
I wonder if Intuit even cares that a large number of TT users will probably be using some other software next tax season!!!
