The debug log is located in the folder C\:ProgramData\VMware\VDM\logs folder.Please refer to Location of Horizon (VDM) log files (1027744) for more details.
Cause
This error happens if the following folder is existing (even if it's an empty folder.)C:\Program Files\VMware\VMware View\Server\jre\lib\ext
Typically the folder is removed during upgrade installation.In edge cases, This folder can be left undeleted after an upgrade. (permission issues etc)
The Java version used in Horizon 7.13 and onward does not support the ext folder extensionTherefore , it fails to start the Java Virtual Machine(JVM) if found in the classpath location.
Resolution
Delete the "ext" folder from jre location from where connection server is installed and then reboot the connection server.Example Path : C:\Program Files\VMware\VMware View\Server\jre\lib\extIf you still can't access Horizon Console after reboot, please try to uninstall and re-install Connection Server after remove the folder.To uninstall Connection Server, refer to Removing a Connection Server or a Security Server from a Horizon Pod (1010153)
