SmartThings issue

I installed Home assistant on a Raspberry Pi 2 (I have a raspberry pi 4 running Pi Hole and HomeBridge so I assumed it was to much for Home assistant)

I initially managed to run the integration setup with an error (after showing a link with my Local IP)
After restart I can even run the assistant anymore, every time I’m selecting SmartThings it’s go back to the list of integration (and no SmartThings is not on the enabled integration)
