Most likely are differences in the grounding of the two connected systems. Hot-swapping is worth avoiding. The fact that the previous setup did not do this suggests that it is a connection issue.

Grounding may be tricky, Since the experience when I measured 80 V !!!! between two grounds in one room, I always plug all gear to one common plug.

And even smaller voltage difference fries any chip…..
