Wrapped belt

Moin Together, after 80,000km and frequent on/off my driver belt is slightly worn at the edge. Question is to what extent this condition (see picture) actually influences the safety, i.e. risk of tearing. Of course, the TüV has to monetize this, but an exchange also costs less than 500 euros. I want to protect the affected place first with a protective pole against further stress. What is your opinion on this? Many greetings, Gerd
