Why does my project crash after converting to 4.3?

Hi,

I got one big Problem. I bought the UE 4.3 update yesterday and converted two of my projekts. One of it is damaged now, so i cant start it in any version since 4.0. The second one is maybe ok, that meens i can start it.

So after this i thought i just have to create a new projekt but there i get the problem that every level exept the Default one crashes at saving, even if ther is nothing in it. I dont know what i have done wrong.

I already updated my driver and doublechecked things like the Firewall and my AnitVirus Programm.

The crash report is very short ill post it under this post (its always the same, at “start crash” and “at saving crash”)

Hi siebencorgie,

Does this only occur to projects that you are trying to convert? For instance, have you attempted to start a blank project with no additional content in 4.3?

I did this, with additional content it crashes with a fully blank projekt it works correctly. But after coping things in it, it starts crashing .

The problem is, that i have worked at this projekts for mutch more than 100 h so i dont wanna loose them.

Hi siebencorgie, Have you tried opening it in any other updates? for instance, try to open the project in 4.1 or 4.2 to see if you still get the same crash.

Thanks for your reply,

i converted a copy to 4.2.1 there everything works fine. I can save and do everything i want without any error.

After this a i converted a copy from the 4.2.1 File to 4.3 there also everything works fine, so i think you solved it.

I still dont know what was wrong with the first 4.3 File but know it works so thats good.

If you need somthing from me for Bug research or something, ill try to provide it.^^

Thanks

If you can post a log of the crashes you were getting that would be very useful! You can find these in the file /Unreal Projects/PROJECTNAME/saved/logs/.

i cant upload them, the filetype is not allowed :frowning: I tried the
“.dmp” files and my two “.log” files…

Hi siebencorgie,

You should be able to upload them via a . file. You can also upload them to an FTP server such as dropbox and I can pick them up from the link.

hi,

i uploaded the files here.

hope this works

Hi siebencorgie,

Can you post your dxdiag as well? Thank you!

link text

there it is ^^

Hi siebencorgie,

Unfortunately I still cannot see what could be causing this crash. If you are comfortable with it, I would be happy to take a look at your project and see what might be occurring if you post it here!

im not able to uplaod the projekt, because my dropbox is full:( do you know an other placce where i can upload it ?

Hi siebencorgie,

I will be emailing you momentarily with further information.

Hi siebencorgie,

Have you been able to get the trouble project together so I can have a look?

Not realy, it always has a size about 2gb, also it doesnt has the bug anymore under 4.3.1.

Oh I’m very happy to hear that! I will mark this as answered then for tracking purposes. If this bug re-surfaces please let us know here!
