Win10, latest DLC, CPU environment, running on Spyder

I installed seaborn on the dlc-windowsCPU environment to get some analyses done, which was fine, but when trying to run the code again and import the dlc library, I got the following error:

ImportError: Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'qt5' is currently running

I've uninstalled seaborn from the environment, but the error remains, and couldn't find an easy fix on stackoverflow. I've also made sure tk was installed [qt v5.9.7; tk v8.6.8]

Is there a solution to this problem?
