Hi, i get this error random and don’t know what happened. When deleting project folders except content, i can launch few times, but then get this error again. I launched fine my project to phone, then in unreal engine switched a simple boolean on (enable play a sound ingame) and when tryed to launch again, get this error message. I can build the project and install with install.bat, but cannot launch on my device. Total no idea what happened. Not added any fbx today, only a wav and a png file Engine is 4.21.1 Please help me [ATTACH=JSON]{“data-align”:“none”,“data-size”:“full”,“data-tempid”:“temp\_154677\_1546066452055\_321”,“title”:“0\_UE\_4\_error.PNG”}[/ATTACH] [https://forums.unrealengine.com/core/image/gif;base64](https://forums.unrealengine.com/core/image/gif;base64) ​ ---

I have no idea what’s going on. Mine happened completely random and I can’t figure out what has happened. I’m going to try move everything I need into another project and just start fresh. Annoying but no-one seems to have this issue or a solution. ---

Hi! I had the same problem while trying to package to Oculus quest. Found this [instruction](https://adamosk.com/attempt-to-construct-staged-filesystem-reference-from-absolute-path/)that helped me: Type in command prompt: C:\Users\adamos\> **adb shell** hero2lte:/ $ **cd sdcard** hero2lte:/sdcard $ **ls** Alarms DCIM GSWave Music Pictures Podcasts Samsung Android Download Movies Notifications Playlists Ringtones UE4Game hero2lte:/sdcard $ **rm -r UE4Game/** **Edit:** FYI. That “ls” is (LS) with small letters. Thanks for the clarification! ---

Your SD card (or internal storage, depending where you’ve set your project to dump the files to) may be full! I’ve had the same issue and it seemed random too until I noticed that the SD card on the phone was packed full. I made some space and it worked since. I think it explains the few times it worked for you until the new files packed the SD card full again. ---

I advice to check out the link as the formating in this post is incorrect. Also its not a 1’s as Mentioned(ones). Its LS lowercase. ls is listing off whats in the sdcard, so you can pick the folder to delete. Open Command Prompt as Admin, and Type: adb shell Then type: cd sdcard Then type: ls (which is lowercase LS) This will give you a list of jazz, pick which to delete. ie: Alarms DCIM UE4Game etc etc Then type: rm -r UE4Game/ (this deletes all in that folder) Good luck. Note, To delete games from Oculus Quest, that are unknown sources, you can use this command: open cmd as admin and type: adb uninstall com.YourCompany.Nameofgame (note: com.YourCompany.Nameofgame is from project settings-Platform-Android- Android Package Name) Cheers ---

I can confirm, deleting the UEGame directory on the root helps. ---

Still happening on 4.27 and Quest 2, potentially also on 5.1 . You can use the following code to automate the deletion - just paste that code in a .txt file, rename it to .bat afterwards : ```auto adb shell "cd /sdcard/; rm -r UE4Game/ " pause ```
