Method call would cause a deadlock to occur

I´m facing the following error with my application ASP.net:

Unable to cast COM object of type 'LBCOMLib.LBCOM_SessionClass' to interface type 'LBCOMLib.ILBCOM_Session'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B46EBC80-9D0D-11D3-B0D3-0000B422F6DA}' failed due to the following error: The component is configured to use synchronization and this method call would cause a deadlock to occur. (Exception from HRESULT: 0x8004E005)

This is happening when I call a page of search on the application. Weeks ago it was working, but now even if I put breakpoints at all methods of the page.cs even Page_Load while debugging the system doesn´t stop at the breakpoint and pops up whith the error described before.

Does somebody explains what´s the problem?

Solution 1:

Try to UnCheck

COM object viewable checkbox

under the VisualStudio Settings

Solution 2: Try to browse from over the Asp.Net server URL link

This is interesting with the ComVisible attribute in your AddIn project probably Activex Ocx etc.
