SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

Solution

When the SQL Server starts it tries to open listening named-pipes to accept client share memory or named-pipe connections. If the listening named-pipes are not closed properly during the last shutdown of SQL Server (maybe after a forced kill of the SQL Server process), there will be orphan named-pipe handles in the windows kernel file system.

To solve this issue, a quick solution will be to reboot the machine hosting the SQL Server.
