Possible regularisation for sum of function of primes

Consider the following sum of function of primes:

$$-\sum_{p}\ln\left( 1 - \frac{1}{(ep)^{1/2}} \right){\ln(p)}$$

Here $p$ runs through all primes and $e$ is Euler's constant.

We can see that the sum diverges.

I have following questions :

Is possible to regularize this sum ? If yes, how to do so?

Any advice about going around this is welcome. Any insights in such type of problems is/are also welcome.

Tried doing so using proof of Merten's theorem but failed!
