It may be worth trying the latest official Ethernet library from Arduino Library Manager. Also, try removing the E-RST jumper from D11/D12, since those pins are used by SPI on the UNO R4 Minima.
Then initialize the W5500 with:
Ethernet.init(10);
Ethernet.begin(mac, ip);
After removing the jumper, fully power-cycle the boards and test again.
