+## Known issues

+### The `SteamLinuxRuntime_sniper-arm64` issue
+
+If Envision crashes with this in terminal/logs:
+
+```
+thread 'main' panicked at src/util/file_utils.rs:165:9:
+Failed to copy /home/USERNAME/.local/share/Steam/steamapps/common/SteamLinuxRuntime_sniper/_v2-entry-point to /home/USERNAME/.local/share/envision/backups/_v2-entry-point.bak: No such file or directory (os error 2)
+```
+
+This is because [Valve suddenly renamed a folder](https://steamdb.info/app/1628350/history/?changeid=30126564), and it hasn't been reflected in Envision yet. Anyone who has installed or moved the runtime since 18 July 2025 will run into this, even if they are not using ARM64. For now, please symlink it:
+
+```bash
+ln -s ~/.steam/steam/steamapps/common/SteamLinuxRuntime_sniper-arm64 ~/.steam/steam/steamapps/common/SteamLinuxRuntime_sniper
+# or if it's located on a different drive e.g. /mnt/steam
+ln -s /mnt/steam/steamapps/common/SteamLinuxRuntime_sniper-arm64 /mnt/steam/steamapps/common/SteamLinuxRuntime_sniper

 ## Experimental feature settings
 
 The following resources can be entered into your Envision profile repo and branch settings to enable early access to code before it's fully upstream in Monado itself. To enable these feature sets, simply clone your profile, edit it with these settings, then build.
