Got mine to work.
I noticed mine would intermittently quit after the "You're up-to-date" message. Didn't fail every time. My 2024 TT file was saved on a Mac in the Documents folder which happens to also be on iCloud. I move the file to a different folder and TT launched completely without quitting. This could be a timing issue for files saved on iCloud, not sure but iCloud caches files locally before they are saved to the Cloud. Perhaps the state of the file makes a difference to TT when trying to launch the App? Just guessing, but moving the file allowed TT to launch. Some of you reinstalled TT under a new User and that would also provide a new file as opposed to opening an existing one. Some of you renamed or compressed the file and that also would cause TT to open a new file. Bottom line, if TT can't find the last file you worked on in place it was last saved, then it launches OK to a new blank file. Then you can open your saved file OK.
