Sync 3.4.20351 - Feedback & Issues

I tried to update my Sync3 from 3.0.12950 to 3.4.20351 and I’m not having much success.

I keep getting the same error:

Error in 4U5T-14G423-BB_1598634411000.TAR.GZ

Vehicle" 2016 Mustang GT Premium
Non-Navigation model

I’ve tried 3 different flash drives with the same result.
SanDisk 64GB Extreme USB
SanDisk 64GB Cruzer USB
Generic 16GB

Thanks for any suggestions.
