Why does Palworld 1.0 crash on startup for some PC players?

Leftover Early Access mod files (.pak, UE4Mod folders) cause startup crashes even after unsubscribing on Steam Workshop. Fully delete mod files from the Palworld install directory — disabling mods in-game is not enough.

Should you back up your save before updating to 1.0?

Yes. Copy your save folder before launching patch 1.100.427. Dedicated server owners should snapshot world saves and wipe incompatible mods before updating the server binary.

Are there official hotfixes after July 10, 2026?

Yes — post-launch chain: 1.0.1 (July 15) → 1.0.2 (late July) → PC mod hotfix 1.0.2.100993 → World Tree infinite-loading fix 1.101.103 (July 30–31). See Version 1.0.1, 1.0.2, 1.0.2.100993, and 1.101.103 pages. Mod conflicts may still need separate workarounds.

How do you fix mod-related crashes?

Navigate to your Palworld install folder, delete Pal\Content\Paks\~mods or third-party .pak files, remove UE4Mod directories, and verify game files on Steam. Restart without any mods enabled.

Does Palworld 1.0 require a new save?

No — saves upgrade automatically. If a save corrupts after update, restore from backup. Fresh Start is optional for players who want clean 1.0 progression pacing.

What should dedicated server hosts do at launch?

Update server binaries, remove EA mods, enable new voice chat and guild settings if desired, and size CPU/RAM for the launch player spike. Server clustering groundwork exists but is not player-facing yet.

Palworld 1.0 Launch Troubleshooting

Palworld 1.100.427 is the largest update in the game's history — and launch week surfaced predictable friction: leftover Early Access mods, save anxiety, and performance complaints on certain hardware. Pocketpair warned players to delete mod files before updating, not just disable them. This page collects verified fixes and a pre-flight checklist so you reach Sunreach and the World Tree instead of fighting the launcher.

July 2026 patch line: Stuck in infinite loading after the World Tree boss? Install build 1.101.103 — see World Tree hotfix notes. PC players using mods should verify they are on 1.0.2.100993 or newer after the late-July 1.0.2 patch.

Delete Mods — Do Not Only Disable

Unsubscribing on Steam Workshop does not remove .pak files from disk. Browse to your Palworld install (Steam → Properties → Installed Files → Browse), delete third-party mod folders and stray .pak files under Pal/Content/Paks, then verify file integrity. Restart the game before spending hours troubleshooting GPU drivers for what is actually a mod conflict.

Save Backup Checklist

Copy %LOCALAPPDATA%\Pal\Saved\SaveGames to external storage
Note your Steam ID subfolder — restores must match the same folder
Dedicated servers: snapshot Pal/Saved/SaveGames/0 before binary update
After confirming 1.0 loads, keep one pre-1.0 backup for a week

Known Post-Launch Issues (July 2026)

Patch chain: 1.0.1 (July 15) → 1.0.2 / 1.100.933 (late July) → PC mod hotfix 1.0.2.100993 → World Tree infinite-loading hotfix 1.101.103 (July 30–31). Remaining reports include UE-Pal Exception Access Violation on unclean modded installs, startup loops with old mods, and AMD configs without FSR. Consoles see fewer mod issues — let multi-GB patches finish downloading.

First Steps After a Clean Launch

Read the fresh start guide if progression feels overwhelming. Veterans should audit base automation, then follow Sunreach unlock → Auri tower → Panthalus for the intended 1.0 story route. Full feature list lives on version 1.0 patch notes.
