Feature messages keep popping up in Visual Studio Community 2026
Those messages report failed language-service activation and a lost JSON-RPC connection, so hiding feature notifications would not resolve the underlying problem. The exceptions alone do not identify why the remote service stopped.
Your reported Windows build, 21996.1, is outside the currently supported Windows 11 releases. Visual Studio 2026 requires a supported operating-system version. Before further cache resets or CET changes, reproduce the issue in a persistent VM running a current, supported Windows release and an updated Visual Studio installation. KVM/QEMU by itself is not enough information to establish the cause.
On that supported baseline, start Visual Studio with devenv /SafeMode to compare behavior with the default environment and services. Also run devenv /Log to capture ActivityLog.xml, then reproduce the failure.
If it persists, use Report a Problem with the exact Visual Studio version, VM configuration, logs and reproduction steps. Include that repair and cache clearing already failed.
