My R8 chassis is connected to R4, and then connected to Macbook pro2021 through Thunderbolt 3 to Thunderbolt 2. Yesterday, I found that the power strip was not powered on, and I was shocked by the Thunderbolt 3 interface. I tested it with a pencil and found the Thunderbolt 3 data. The cable has electricity, and the R8 case also leaks electricity. When I connect the computer, the case will not leak electricity when the case is working, which makes me very puzzled;

Will this cause damage to the laptop? And it will shock people, the voltage should be relatively high.
