### Summary

Two players reported that after playing our island Rocket Wars, they get removed from the match with an error saying there are installation issues and are told to verify or reinstall Fortnite. The issue keeps returning and only affects our map.

### Please select what you are reporting on:

Creative

### What Type of Bug are you experiencing?

Stability

### Steps to Reproduce

1. Join the Rocket Wars map
2. Play for 15-20 minutes of gameplay
3. Observe crash, attempt to requeue and get Fortnite must be reinstalled error:  
“You were removed from the match due to errors in your installation. Please verify or reinstall Fortnite to correct these issues.”
4. A full reinstall of Fortnite temporarily resolves the issue but returns again after 15-20 minutes

### Expected Result

Players should be able to load and play Rocket Wars without encountering an error that forces a full Fortnite reinstall

### Observed Result

Two players have reported that, after some time playing Rocket Wars, they are unable to load into the map and are met with an error that states they must reinstall Fortnite

- Other Creative maps work fine during this time
- Reinstalling Fortnite allows them to play Rocket Wars again, but the issue reoccurs after ~20 minutes
- Switching rendering modes (DirectX 11, 12, Performance) did not resolve the issue

We’ve reviewed game logs and replays but haven’t found a clear cause

### Platform(s)

Windows PC

### Island Code

5196-0233-5799

### Additional Notes

I’ve compiled Fortnite Game logs, Dxdiag, replays and a video demonstrating the issue in this shared Drive folder: [Rocket Wars Reinstall Issue - Google Drive](https://drive.google.com/drive/folders/1ubJ5kS8MgL_zrv-wQ4_eR8MWwCeXADkh?usp=drive_link)

When the player tries to Verify files, it makes them reinstall 70 GB of files and afterwards the issue still persists.

hi @OniZach ,  
Island 5196-0233-5799 works on Samsung Android very well, Nintendo Switch 1 works, Xbox One x works. Android Phone over 30 minutes, tried Teleports to different team games all over, killed many times still in games.

Therefore its a PC problem.  
My best guess is the anti virus checker is seeing part of the Fortnite games and isolating them as virus parts, or there is a virus on PC and its not been detected.

The Easy Anti cheat detector is detecting corruption and throwing them out.  
Consoles are not affected.  
During the game on console a big black blank screen comes up and then the games restarts.  
Oh yes tested on 36.30 so its not version dependant

I would’ve also assumed it would be their anti-virus or something else on their PC causing it but they can play any other creative island just fine without issue, it’s **only** Rocket Wars.

I’ve asked one of the players if they have any third-party anti virus software installed and they do not, just Windows Defender, but to be sure I’m having them do a Full Scan, then if no results, turn it off and seeing if the issue persists (they need to reinstall Fortnite again first which may take a bit). Will reply here with results.

Hi @OniZach ,  
Just opened a Rocket Racing Epic Island and now my PC/laptop is running low on memory space, the reason is reduced Virtual Memory, now Rocket Racing Epic Islands get a problem running low on virtual memory.

Now put the Page file back to 32GB and working smoothly again

To add this, see the post

[How to add 32GB virtual Memory page file](https://forums.unrealengine.com/t/cant-create-c-project-or-use-c/238169/2)

Before re-installing Fortnite

Under Windows 11, there was a problem where when the disk became full, the disk structure could have errors remaining. This can be fixed by opening the Windows command shell,l right-clicking and running as administrator

```auto
C:> chkdsk /f/r C:

```

Now restart the PC, and the disk is scanned for errors and fixes any errors.  
This applies to ALL Windows versions.
