Rider 2025.3 auto builds project on focus lost

I just updated to Rider 2025.3 on Linux Mint and it's now building my project every single time I tab/click away from Rider. This has already caused Godot to throw an error at least once saying that the .dll it needs couldn't be written to and I see no need for Rider to build the code as I still have to tell Godot to re-build and re-load it anyways.

How do I disable this?

Here's the exact version info:

Using the same version of Rider, I have the same problem on fedora 43.
