The file name extension for last year's file should be .tax2024, not .tax_2024. This could have something to do with your problem. It looks like you either changed the file name or you are using the wrong file.
Note that you cannot open a 2024 file in the 2025 software. You can only transfer the data from 2024 when you first start your new 2025 tax return.
You have added on to a long thread that is nearly a year old and is only superficially related to your problem. The details are entirely different. I suggest that you post a new separate question of your own. In your question, be sure to explain exactly what "refuses to load" means. Exactly what happens when you try to transfer the 2024 file? At what point does the problem occur? If you get an error message, what is the entire exact message? Do not answer these questions here. I'm just giving you a suggestion for what to include in your new separate question.
