Cant Open edit setting of any vm

I am receiving a timeout error whenever I try to edit Resource Allocation on my virtual machine. Error is below

Call "EnvironmentBrowser.QueryConfigOption" for object "1-envmgr" on ESXi " ESXi Name" failed.

I have tried from other servers and other operating system and other version of vsphere clients. There is only one esxi server here and we manage it as standalone.

A help will be appreciated.
