Encryption RSA strange problem

Hi Guys,

I have a strange behaviour with a copy of a pipeline. I made a duplicate and tried to change the value to make it works for a different source but the encryption stopped working for the new pipeline. So i made another one, then i made it from scratches but the problem is always there. In addition, it's seeems to have affected any new pipeline i have made.

I removed the "try/catch" on the function and i get an error saying "the provider for the RSA hasn't been found, but on the others old pipelines the encryption still works.

Can someone help me if already solved this problem?

Thank you.

PFB the code i use.
