Since folks are starting to use SAMD51...J20 and J19 there are now separate bootloaders for each chipset. Make sure to use the correct one!
If you can access bootloader mode (double-click reset button), you can copy over the respective update-bootloader UF2 to update the bootloader without having to use JTAG.
