Do you have a reliable, preferably 'official', power supply for your RPi4b?
Since you have mentioned two "Microsoft" filesystems, perhaps you intend to use this thumb drive to transfer data to some sort of Windows system?
Have you tried formatting the storage device on the Windows system it will be used with?
Maybe the thumb drive device is faulty? Have you checked it with any other systems to confirm it works?
