I’m new to Azure portal and DevOps in general.

Some context:
I recently created a new App Service(Web app) in azure which will be my production environment.
I used the same app plan as my UAT environment(in case this matters).
I followed the process for registering a custom domain etc.
This web app is successfully connected with my DevOps Repository as well.

Issue statement:
The problem that I have at the moment is that when I run both the Production web app and the UAT web app simultaneously, I get an exception that reads:

Application: w3wp.exe
CoreCLR Version: 8.0.524.21615
.NET Version: 8.0.5
Description: The process was terminated due to an unhandled exception.

The short-term solution I’m using is keeping the production web app deactivated, as users are still using the UAT environment anyway.
How do I get a permanent solution for the above exception that allows me to run both web apps?
TIA
