Hey MOON LEGS,
Looking closely at your Player.log, your crash happened because the game engine ran into a critical file-reading error the exact moment it tried to stream the audio and music data for the Eikthyr raid event (Random event set:army_eikthyr).
The key error lines are here:
• Failed getting load state of FSB for audio clip "ForestIsMovingLv1"
• Archive file was modified while it was opened, and can no longer be accessed... \SoftRef\Bundles\61c598bb
• Failed to read data for the AssetBundle...

🔬 What exactly happened?

When the raid triggered, the game tried to open its compressed asset archives to pull out the background music track. However, Unity detected that the asset archive bundle files were either corrupted, missing data blocks, or suddenly locked by an outside background process on your laptop while the game was actively reading them. This caused the asset loader to panic and crash your client.
On your specs (i5-13430H and an RTX 4050 Laptop GPU running standard Win 11), this is almost always a file-system conflict rather than a hardware issue.

🛠️ How to fix it (Step-by-Step)

Here are the three methods to clear this up completely:

1. Verify Game Files on Steam (Most Likely Fix)

Since the game can no longer read data blocks inside your SoftRef\Bundles folder, you need to let Steam scan and repair the corrupted audio archives.
1. Open your Steam Library.
2. Right-click Valheim and select Properties.
3. Go to the Installed Files tab.
4. Click Verify integrity of game files.
5. Let Steam run its pass. It will automatically detect any broken bundle files and redownload clean, working copies.

2. Whitelist your Valheim Folder in your Antivirus

The error Archive file was modified while it was opened happens when an outside program (like Windows Defender, a third-party antivirus, or a cloud syncing tool like OneDrive) tries to scan or touch your game files at the exact millisecond Valheim opens them, creating a file write-lock.
• Go into your antivirus settings and add a Folder Exclusion for your specific drive library path:
D:\SteamLibrary\steamapps\common\Valheim\

3. Clear Out Old Mod Residuals (If you ever used mods)

If you are running texture replacers, custom audio mods, or old manual overrides that place custom assets straight into the StreamingAssets directory, they can conflict with vanilla game updates.
1. Navigate to: D:/SteamLibrary/steamapps/common/Valheim/valheim_Data/StreamingAssets/SoftRef/Bundles/
2. If there are manually added loose mod files in there, delete them.
3. Run the Verify integrity of game files step on Steam right afterward to guarantee a perfectly clean baseline.
Give the Steam file verification a shot first, and you should be completely good to handle your next forest raid without any crashes! Let us know if it works.
