To evaluate the integral:

\[
\int \frac{\left( \cos^{-1}(x) \cdot \sqrt{1 - x^2} \right)^{-1}}{\ln \left( 1 + \frac{\sin \left( 2x \cdot \sqrt{1 - x^2} \right)}{\pi} \right)} \, dx
\]

we need to examine the components of the integrand carefully. Let's break it down:

1. **Numerator Analysis:**
   - The term \(\cos^{-1}(x)\) is the inverse cosine function, which gives an angle \(\theta\) for a given \(x = \cos(\theta)\).
   - \(\sqrt{1 - x^2}\) is part of the expression that often appears in trigonometric integrals, related to \(\sin(\theta)\) when \(\theta = \cos^{-1}(x)\).
   - The entire expression \(\left( \cos^{-1}(x) \cdot \sqrt{1 - x^2} \right)^{-1}\) represents the reciprocal of this product.

2. **Denominator Analysis:**
   - The term \(\sin \left( 2x \cdot \sqrt{1 - x^2} \right)\) suggests a trigonometric function that might be simplified using identities or substitutions.
   - \(\ln \left( 1 + \frac{\sin \left( 2x \cdot \sqrt{1 - x^2} \right)}{\pi} \right)\) appears in the denominator, which complicates direct integration.

### Potential Strategy:
Considering the complex form of the integrand, a direct integration might be infeasible. However, some possible approaches include:
- **Substitution:** Trying a substitution for \(\cos^{-1}(x)\) or the expression \(\sqrt{1 - x^2}\).
- **Trigonometric Identities:** Simplifying \(\sin(2x \cdot \sqrt{1 - x^2})\) using trigonometric identities.
- **Numerical Methods:** If a symbolic approach is challenging, a numerical approximation might yield a solution.
