Hello there @chrissun14!
Considering that 5.6 has just been released, it is prone to have unexpected issues, so the most immediate solution would be to roll back to 5.5. Still, we can try a few solutions here:
Your error “Resource Default.rc2: Exited with error code -1” is usually tied to issues between the compiler, your current SDK, and your visual studio’s installed components.
Per 5.6, the VS 2022 version compatibility is for 17.8 or later (17.14 recommended). Please check all components of your VS current install, you can find the details for this process here:
After that, test by cleaning up your project, via deleting Saved and Intermediate folders, then re-open your project. The newly generated files should work with 5.6. You can re-generate your project files in VS, as well.
