"Reference to an object not set on an object instance" while trying to add a term in Studio 2019's Editor

Question

Dear all, 
 During a project, I'm currently unable to add terms on the fly to an active termbase because whenever I try to do it I get the "Reference to an object not set on an object instance" error message. A quick search on this forum allowed me to see that this error message is very common and ofter appears in different scenarios, but I haven't found a thread particulary related to adding terms. 
 For the record, the termbase is open and I get the results in the termbase results pane, and AutoSuggest from the TB appears to be working. The error message only appears whenever I try to add a new term. 
 Can you help me? What can I try to solve this particular problem? 
 Thanks in advance, 
 Dami&aacute;n

Hi Dami&aacute;n Santilli 
 First, if this is only happening with one termbase, reorganising that termbase may help. This is done by opening the termbase in MultiTerm and clicking 'Termbase Management' at the bottom of the left-hand pane, then Reorganise on the top toolbar: 
 
 Click through the Wizard then Close. 
 If it's happening with one or all termbases, does it still happen if you change from the default layout of the termbase window to, for example, flags layout? 
 
 Next, have you pinned Termbase Viewer or is it pop-out? Pinning it can stabilise things. Or unpinning then pinning - or resetting the whole view via the View tab>User Interface>Reset Window Layout. 
 Also important, do you have the correct version of MultiTerm for your version of Studio and have you made sure your version of MultiTerm is up to date? To do this, if you have automatic updates set, just open MultiTerm and accept any update offered. If you don't have automatic updates set, open MultiTerm and go to Help > Check for Updates. 
 Then, have you tried a Windows Repair of Studio via Control Panel? Instructions of how to do this, plus other ways to reset your Studio/MultiTerm setup, are given here: 
 Repairing your installation of SDL Trados Studio 
 
 Performing the first suggestion, a Windows Repair, is helpful with any heavy-duty software, especially after an update. BTW, y ou can find Control Panel by typing it into the 'Type here to search' box next to the Windows button bottom left of your screen. 
 Then repair MultiTerm: 
 Repairing your installation of SDL MultiTerm Desktop 
 Instructions for resetting Studio and MultiTerm are also in the above two links. 
 I would imagine running through the above will solve your problem. If these suggestions don't help, then try reinstalling. 
 If that does not work, you can then get free help with installation issues that are preventing you from working, pretty fast: 
 
 Fill in the form here: 
 installation and licensing help 
 Select 'Installation' from the 'Case type' dropdown and tell them that the problems occurred after installation and, most importantly, give your correct email address so that they can contact you. 
 I hope that you can find a solution in amongst all of the above!

Hello Damián Santilli , 
 Thank you for sharing the error message. 
 This is however too generic unfortunately to be of any help. 
 Please expand the message - 
 
 Also please be advised 
 You can also post the entire message - 
 
 If you have recently updated/upgraded your Studio version, then you must also update MultiTerm as well. 
 The following Wiki's also help resolve many issues-
