Prefabs in 2020 taking 10 minutes + to import

When I add a prefab to my project the import time during startup, reload, or refresh goes from seconds to minutes. Before I removed the roughly 20 Image prefabs I had the import time was 1.5 hours. My project is small but nearly complete and this is incredibly frustrating.

What do I do? I could instantiate fresh objects and add components to them and set the values but this is a mobile game spawning objects quicker than every second so I imagine the performance hit would be huge.

Please let me know what is going on, and if the Unity team can help that would be great, this is a huge issue. Thanks.

Which version of Unity are you on? There were some performance regression introduced during the beta but they should all have been resolved.
