  • I have two computers; one a Chromebook and the other a Windows 10 PC. I've repeatedly had issues with being unable to open Construct 3 projects only on my Windows. I'm able to open all of my projects with no issues on my Chromebook.

    I save my projects to Google Drive.

    It either gives me the message 'Failed to open project.' or 'Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project.'.

    This issue has previously been caused by effect plugins, but I've made sure that I have all of the plugins that are used in the project installed in Construct on my Windows and that all of them seem to be working as intended.

    I've tried using f12 and got the errors 'Failed to load resource:net::ERR_BLOCKED_BY_CLIENT' and 'Failed to load resource:net::ERR_FAILED'.

    It also might be worth noting that the last time the project was edited shown in recent projects is incorrect and earlier than it should be.

    I would really appreciate any help I can get.

  • Are you using the latest version of C3 on windows? I’ve had c3p files fail to load in older versions of c3 if they were saved in newer versions. It helpfully points out that the file was saved in a newer version or just gives that error. Even reloading c3 sometimes fixes it.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads

  • Thanks for responding.

    The issue was fixed by clearing my cache and cookies, then closing Construct which uninstalled addons. I then reinstalled the addons I was using (screen space 3D lights and tint blend) which allowed me to open the project.

    Edit, the issue happened again.

  • The exact same issue happened again and it's affecting all my projects with plugins installed. I'm getting the same errors as before. I've tried doing everything I can to fix it, but nothing is working.

  • It's much easier to help if you can share the full text of any error messages. Also, do you have any browser extensions installed? If so try disabling them, as they can often interfere with Construct and cause problems.

    ERR_BLOCKED_BY_CLIENT usually means something on your computer decided to block Construct loading something. So it's quite possibly a browser extension that's blocked a resource Construct needs to work correctly, which then subsequently causes an error.

    I had Kaspersky installed. After removing it Construct seems to work mostly fine although I occasionally get errors.
