Errors with the Integral function

Hello!

I am using the "integrate1d" function in the iteration loop of a Monte Carlo study, but it often gives me one of the following errors:

1. 'integrate1d' failed: Desired tolerance not achieved inside of allowed maximum subdivisions, OR
2. 'integrate1d' failed: Round-off error detected which prevents requested tolerance from being reached.
   Error estimate may be underestimated.

How can I prevent such an error?

Thank you in advance for providing guidance!
