NullPointerException after opening the week1-000.sandbox course about tmc-intellij HOT 3 OPEN

Hmm, followup;
In an attempt to open the next assignment I opened the TMC menu on the top of the screen and pressed 'open TMC exercise list'. The list loaded and I tried to open the first (000.sandbox) exercise and IntelliJ went completely grey. The top menus do open when pressed, but the open TMC exercise list button doesn't work anymore.
After trying the next exercise button this nullpointerExpection appeared:

Hi, sorry for taking so much time to get into this. I managed to fix the latter bug, but the first one was a bit trickier to reproduce. In case it's still bothering you, could you try updating to the newest version of the TMC plugin (v2.0.2) and see if the error still occurs?

Having the same problem at the moment after updating to 2.0.3
