What's Wrong?

Claude Desktop displays "Failed to load marketplaces" with the following error:
Error invoking remote method '$eipc_message$_0fb61ed5-aa65-44a8-bb2b-ac97e15fc04a_$_claude.web_$_CustomPlugins_$_listMarketplaces': Error: VM is not running. Start a conversation first.
Restarting the app and "Try again" do not resolve the issue. The VM/sandbox powering the marketplace never initializes.
Environment:
Device | ASUS Vivobook S (Snapdragon X Elite)
Processor | Qualcomm Snapdragon X Elite
Architecture | ARM64
OS | Windows 11 Home 25H2
OS Build | 26200.7922
Experience Pack | Windows Feature Experience Pack 1000.26100.300.0
Claude Desktop | Latest version (as of March 2026)
Expected Behavior
Marketplace should load normally.
Actual Behavior
VM fails to start, marketplace never loads.
Related ARM64 Issues
This appears to be part of broader ARM64 compatibility problems:

#28529 (Desktop fails to render on ARM64)
#28779 (ARM64 installer silent failure)
#27677 (Bun runtime panic on ARM64)
#28184 (Failed to load session on ARM64)
#13251 (ACCESS_VIOLATION on ARM64)

ARM64 Windows devices (Snapdragon X, X Elite, X Plus) are shipping in high volume from Microsoft, Lenovo, Dell, HP, ASUS, and others. Native ARM64 support should be a priority.

What Should Happen?

Marketplace tab should load and display available plugins/integrations without errors.
