Both String Trimmer and Edger work great, easy to start and very low vibration.

I have run onto several of the Troy-Bilt with this trouble. Seams the part of the head where the flex drive shaft fits into is weak and gives up. Unfortunately this part of the shaft housing isn't serviceable and the shaft will have to be replaced.

Bushing is worn out. You will need to replace the shaft. Fairly inexpensive.

Remove the angle drive gearbox near the string head and spin it to see if everything is moving properly. You may have stripped the gears out of it.

There is a drive shaft that runs the length of the tube from the head to the motor. If the head is not on the tube completely the head will not spin. There should be a screw or two on the shaft by the head you can take loose, once it is loose you can rotate the head and push on to tube further. If you need any more help let me know, Daniel.

Replace the shoes inside the clutch.

Considering your experience, if I was in your position I would locate the cause of the persistent failure and contact the manufacturer who might be suitably grateful.
I did that once with an inspection light that was bought in from China and brand engineered, as many goods are today, and I received a voucher and the company stopped buying that model. While it didn't help me much it would have helped others.

I am not familiar with the Troy-bilt brand which must be an exclusively US brand. I have used a MAC-60A for 30 years without many problems, a model reckoned by repairers to be a short-lived cheap consumer model.

The majority of the time excessive string feed is caused by one or a combination of one or more of the following:

String wound backwards. Seems simple enough, but happens to the best of us.
Missing or improper spring.
Lubrication ANYWHERE on the shaft or inside the bump head assembly. This item should be clean and dry..but never lubricated.

If you know the model number on your particular trimmer, that would assist in troubleshooting.

I hope this helps.
