I've been experiencing a persistent WEASEL error in Destiny 2 on my Windows 10 PC for months. The game launches normally and reaches orbit, but after approximately 20–30 seconds, I get WEASEL and am returned directly to the title screen. Important findings: Happens on both Steam and the Xbox PC app, with separate installations. Happens on two different Steam accounts. Happens on every character. Happens on two different internet connections. Destiny 2 previously worked on this PC. Destiny 2 works on my Xbox console. Steam stays online when Destiny disconnects. A continuous ping test showed 0% packet loss during the disconnect. Troubleshooting already performed: Verified Steam game files. Checked NAT and UPnP. Reset Winsock and flushed DNS. Removed Hotspot Shield VPN and NetLimiter. Performed a Windows clean boot. Confirmed BattlEye starts successfully. Checked Windows Firewall inbound permissions and outbound rules. Checked network adapters and installed network components. Reset Destiny 2 configuration files. Tested a completely separate Xbox PC installation. System: Windows 10 Home 22H2, OS Build 19045.6466. Could Bungie investigate whether this is a Destiny 2 session or networking issue affecting my PC, and advise what diagnostics would help identify the exact cause?
