There are so many red screen warnings that I can't use my projects properly. There are too many red screens for example sources on the site. Please stabilize it. Construct 3, fighting

How do I get back to the pre-R424 stabilization version?

We had several weeks of testing beta releases with no known serious problems reported before we released a stable update. If we missed something please file an issue following all the guidelines and we will look in to it, but please note we need all the requested details to be able to help.

This plug-in I used has not been updated, so I keep getting errors, so I can't bring up the project. Can't I contact the producer to make this update? I can't find the email even on the homepage. If it doesn't get updated, how can I save my project??

If it's an SDK v1 addon, it is not showing you an error, just a deprecation warning. You might be able to use the built-in CSV plugin instead. Alternatively you'll need to contact the addon developer for an update, or remove it from your project. SDK v1 addons will also still be supported in LTS releases of Construct through to the end of 2026 (about 2 years from now).
