Reload Scripts Assemblies (busy for long time) Unity Freezes

Question

I'm Using Unity version 2020.3.32f1 & Rider as Editor. Whenever I make any changes in scripts, even small changes, Unity script assemblies take too much of time to compile and load. Sometimes it freezes Unity entirely and in the Task Manager I can see "application not responding" for the Unity session.

Does anyone know how I can solve this issue?

Disable Domain Reloading. To disable Domain Reloading:

1. Go to Edit > Project Settings > Editor
2. Make sure Enter Play Mode Options is enabled.
3. Disable Reload Domain
