Level Crash on Startup

Hello,

I went to open my current working project this morning and it was crashing on start up. So I investigated the forums here a bit and found how to remove the default level from the DefaultEngine.ini.

Once I bypassed my default level I was able to get into the project but when I open the level it crashes the project.

I took a look at the log files and found this series of lines:

[2016.08.29-12.36.41:892][140]LogWindows: Windows GetLastError: The operation completed successfully. (0)
[2016.08.29-12.36.42:343][140]LogCrashTracker:

I’m assuming that critical error is what is crashing the level and the project. However I am not 100% sure what it means. I Was messing around with foliage the last time I was working. I saved the project and closed out as usual at the end of the day with no issues, but as of now it will not start up.

Any suggestions on how to deal with this?

Thank you,

Just to be sure, as it seems that its a cache thats messed up:

Delete your “Saved” and “Intermediate” folder from your project and reopen it. Then it should regenerate most caches you got.

Hope that helps!

Cheers,

Thanks for the input ,

I just tried deleting both of those folders and I am still crashing with the same error. Certainly good to know for future troubleshooting.

Do not delete your "Saved" folder - Rename it!

if after renaming it (to something like Saved_bkp) the problem isn’t solved - you can sometimes need a saved backup file or a few from the “Saved” folder to replace the current version if it’s corrupted.

It depends on the cause of the crash if you will actually need it or no, but man don’t make your life harder. you can always delete the backup some time after you solve the crash.
