TV will not start on LinuxMint

Hello, I've used TV on LinuxMint for some some time, however I have a new problem I've not encountered before.  When I click the icon in the menu to start it, nothing happens.  GUI does not start or attempt to start (AFAI can see).    I resorted to executing the launch command from the command prompt to see what happens with this result:

<localhostname>:/opt/teamviewer/tv_bin/script$ ./teamviewer

Init...
CheckCPU: SSE2 support: yes
Checking setup...
Launching TeamViewer ...
Launching TeamViewer GUI ...
<localhostname>:/opt/teamviewer/tv_bin/script$

Again, GUI does not lauch.

I then checked the log files, and found the following in TeamViewer15_Logfile.log

2020/01/04 17:25:22.292 14110 **Please do not post TeamViewer IDs**** G!! ResourceLoader: loaded file '/opt/teamviewer/tv_bin/resources/TVResource_en.so' version () is not matching with application version (15.1.3937), Errorcode=2

This is followed by many other errors of  No session found!, Errorcode=11

I have installed both from Software Manager and from the .deb file downloaded directly from TV., and having deleted all application directories between each install.   Can someone tell me how to resolve this?
