Hi Vangork, Thanks for the report. A [crash involving ‘High Resolution Textures’ pack](https://forums.unrealengine.com/t/fortnite-ecosystem-38-00-known-issues-thread/2670848) appeared in v38.00 - Do you have the pack installed? If not - Does adding the pack resolve this crash? ---

I got it. The project loaded. The problem was in the Niagara asset. I moved Niagara out of the project and the map loaded. I have 6 Niagara effects here. These only differ in color, which tells me that the problem is not in Niagara itself, but that the file was corrupted during the upgrade. I recommend renaming the folders one by one to find the specific file that may be causing the crash. ---

Looks like the crash depends on verse, when i disable all my verse files the map don’t crash, looks like there is something in verse that is making the map crash, but i don’t know if is the real reason of the crash, what i did was create a blank project and import only my verse files into it, i was able to recreate the crash, even if the project had 0 assets, I hope i helped bi giving to you that information ---

> [@Rock\_Studio](#): > > what i did was create a blank project and import only my verse files into it, i was able to recreate the crash, Hi, Please try deleting each verse file from your blank project, then recreate the crash. Keep a list of the files you delete. When the blank project stops crashing. Then the **last** verse file to be deleted is possibly the faulty Verse file. Upload the last Verse file that was deleted so that others can check and possibly find the problem. ---

Hi! the problem is that the crash is very strange, basically what i did was disable all my verse files and activate them 1 by 1 to see wich one will make crash the map, i have a total of 28 verse files in my map, the first 21 files didn’t cause the crash, then the last 7 works all together so i turned them on all in once causing the map to crash again, so we will say: yes those 7 codes are the main reason of the map crash, but then! if after the crash, i remove the 7 codes and start the map again, the map will CRASH! this doens’t make any sense!, im really sad about this crash becasuse all my work is stopped for this, and i don’t know what to do really. I leave you here the codes of the crash, thank you for the help! [RPG CODES CRASH.zip](https://forums.unrealengine.com/uploads/short-url/nbUhMqAUlRPrqCxLXYWEmr7rNjO.zip) (46.6 KB) ---
