Corrupted files after a data transfer from MacBook Air to MacBook Pro

I recently got a new MacBook Pro. I transferred data to the new MacBook Pro through the migration assistant. Data was transferred from Mac (Macbook Air, old Mac) to Mac (Macbook Pro, new Mac). Now the problem is that there are some files that I cannot open on the new Mac, It is not any specific file type, it's happening with different file types. I logged out of my Apple ID from my old Mac and now when I signed back in to retrieve those files, I can't. Those same files are not showing up on my old Mac now. It was fine before the data transfer and before I logged out my Apple ID, but now I can't see those files on my old Mac, and can't open them on my new Mac. If anyone have any idea how I can get those files back on the old Mac or how can I get them to open on the new Mac, please let me know. Thank you!

Never had your issue.

You can be more specific— what exact file types / what application relation / where ?

You can erase and try again your transfer. Erase your Mac and reset it to factory settings

The most trouble free way to move to a new machine, is using the Setup Assistant on the initial boot of a brand new machine— you have one shot here. Set up your MacBook Pro - Apple Support

The second best way is use the Migration Assistant.

Files are copied to the new Mac—not “moved”…

would look again on your r old Mac.

see about update your third party software (?) if you can not open them , verify you gave “that app” full disk access if that is the issue…
