Importing error - Import unsuccessful

I have been using TT Desktop for years now. I tried to open my previous year to import into the 2024 season. I keep getting warning it was unsuccessful or can't read it. If finds the file, but won't open it. I really do not want to start from scratch again. I have tried to open my 2023 tax file within TT and says it can't open it. I filed my dad taxes last year and it open that file just fine.  I have not been able to locate the Tax2023File, I have all the other years previous. I'm using the same computer.  There are PDF files but it still won't open them, even though it states it will. So, what is the issue? 

Very frustrated with TT right now, I have spent way too much time to get this resolved.
