This sounds like you suspect a general issue on all systems with RTL8125B.
In this case we would have seen another number of reports. So it seems to
be something specific to your system.
What do you mean with "disconnect", you refer to link loss? In this case
root cause may be somewhere on the physical side, e.g. cabling,
RJ45 sockets, link partner.

Note that Ubuntu uses a modified downstream kernel that's not supported
here. Preferably compile a mainline kernel yourself.

Typically the Windows driver is the one best maintained by Realtek. If you
face the issue even with this driver, then it's less likely that root cause
is an issue with the r8169 driver.
