How get totally wiped Sandisk Ultra 3.0 to function again

I use this one for File History and did something which somehow hid the File History file on the disk, then in trying ti find it, reformatted to the default exFAT and now the stick is totally empty and unusable. Windows 10 v 22H2 recognizes the stick in E: indicates "this folder is empty" and it will not accept data since the necessary Sandisk operating files, etc, are gone

Can it be restored factory new?

Well it is fixed despite my best efforts.

To be clear exFAT was in fact the default and I just "re"-formatted it back to exFAT.

I tried another USB stick, this one EMTEC which had no extra Sandisk programs on it, transferred the large file it had to the PC and emptied the EMTEC disk. When Windows still would not load the File History in it, I easily guessed it was a Windows issue and not the USB stick. So I simply renamed the PC's current File History (later deleted it) and simply "added" the Sandisk USB stick again ... and it loaded File History correctly onto the Sandisk Ultra 3.0 for storage. And randomly checked that the File History files were there.

Obviously the Sandisk stick worked without the extra Sandisk protection, etc. software. Then I transferred the large file from the PC back to the EMTEC stick.

Done

Am leaving this "solved" thread in case others encounter the same problem.
