Mac Pro tower (2020) ethernet doesn't work if plugged into an unmanaged switch

I'm trying to connect my Mac Pro tower (2020) to my network using ethernet but am experiencing problems if use my Netgear GS105 switch, this setup results in the MacPro saying "Cable connected but self-assigned IP". I've renewed DHCP leases, changed all sorts of settings including on my router but nothing works, I have also validated that this setup does work fine with every other computer (including a MacPro Trashcan) and if I connect the MacPro Cheese-grater directly to the router it works so to recap: This does *not* work: [Router]----[Switch]----[MacPro2020] This does work: [Router]----[Switch]----[MacPro Trashcan] These also work: [Router]----[MacPro2020] [Router]----[MacPro2020] I've also tried different cables in place of both and and it doesn't improve the situation, every possible combo works except if I have the MacPro 2020 Tower plugged in via the Netgear switch. Is there some issue with unmanaged switches and MacPro 2020 Towers?
