Symptoms

The status bar shows "Indexing..." or "Updating indexes" for a long time, code completion and navigation are unavailable, and fans spin up.

Why it happens

• Huge generated or dependency folders (bin, obj, node_modules and the Unity Library and Temp folders) inside the project root
• Corrupted caches after a crash, update or forced shutdown
• Antivirus scanning the IDE caches and project folder in real time
• Project stored on a slow network drive or synced folder (Dropbox, OneDrive)
• Too little heap memory, so the indexer keeps garbage collecting
