an unhandled exception occurred on the dispatcher thread

[EY_10422330]

I keep receiving the error "an unhandled exception occurred on the dispatcher thread". I have tried different methods presented in the community solution section. However, none did work.

 Hi,

1. What version of the program are you using?

2. Read the following articles:

• "[Knowledge Hub] Error "An unhandled exception occured in the dispatcher thread": https://www.ptc.com/en/support/article/cs323462 
• "Getting error "An unhandled exception occurred on the dispatcher thread" when trying to use Add to quick access toolbar in text formatting within Mathcad Prime 8.0": https://www.ptc.com/en/support/article/cs366338

I am using the latest version prime 8.0.0.0. Every time, I try to put in values or text, the error message appears. I already checked if there was an issue related to net. framework, name of the document, clearing temporary files etc.
