I continue to have this issue after each update. Following the update, the application either crashes or stops responding prior to opening the last used file. Unlike the OP, I do not use DropBox or any other sync.
MacOS Sequoia 15.2
TurboTax Desktop Deluxe 2024
The only workaround I have figured out is to force quit TurboTax (if it just isn't responding), rename my data file. Then, when I launch TurboTax and get past the "No Updates" screens, I get an error that it cannot find my file, so TurboTax opens a new, blank return. I can then restore the name of my existing data file and TurboTax will open it. It continues to work correctly until the next update, then the process starts all over again.
