What's Wrong?

System Information:

• OS: Windows 11 Insider Preview Experimental (Build 26300.8493)
• RAM: 64GB total
• Claude Desktop version: latest

What happens:
Claude Desktop automatically closes/crashes when its memory usage reaches approximately 3GB in Task Manager, even though the system still has plenty of RAM available (64GB total, only 57% used).

Steps to reproduce:

1. Open Claude Desktop (Code tab)
2. Use the app normally for a while
3. Monitor Task Manager — when Claude process reaches ~3.5GB RAM, app crashes automatically

Expected behavior:
App should continue running normally as system RAM is not exhausted.

Additional context:

• Multiple Claude processes visible in Task Manager totaling ~4.5GB
• CPU usage stays at 0% before crash
• System resources are not exhausted when crash occurs
• This appears to be a hardcoded memory limit in the app
