I have a project that was working in 4.10 without warnings or errors. After updating the engine to 4.10.1 I can no longer open the project. There are no errors, windows, or crash reports displayed when trying to open the project from the launcher, I just get a spinning blue mouse cursor and then it stops. I am able to open other projects running 4.9 without an issue.
I am using Windows 8.1, VS 2015. It is a C++ project though I am using several Blueprints as well.
I added my DXDIAG output below. I also checked the Crash logs in AppData but there was nothing, and there were no Project-specific log files under Saved/Logs dating after the update either.
Hey Holodeck-
Is this specific to a single project or are there other 4.10 projects you have that aren’t opening after 4.10.1? Are you able to create/open new projects in 4.10.1? Are you able to run the project from the .uproject in the project folder?
I think this issue is “resolved” though I’m still not certain what the error was.
When I posted my message I was not able to open the project from the .uproject file, nor by selecting the link under “My Projects” in the Epic Games Launcher’s “Library” section.
Per your post I went to create a new project by launching the engine itself with the big yellow button saying “Launch.”
After launching just the engine, I noticed the my project library appeared in another window. When I selected my 4.10 project from this new window, it actually opened (in 4.10.1). Now I am able to open my projects using the “My Projects” library, and I can also use the .uproject file now.
