I lost the link, I did t a lot of searching which kept coming up with
the dhcpcd.conf method and by all accounts many people have problems
similar to what you did where the interface has issues in multi-device
environments.
There's a bunch of threads on places like stackexchange and the Rasberry
Pi foundation blog about the correct way to do this and the vast
majority indicate that the originally suggested method of dhcpcd.conf
(which was introduced in 2015) is too fragile so the two fallback
methods are /etc/network/interfaces and systemd-networkd files or even
NetworkManager (which I don't particularly like in general) but
according to this[1] post on the foundation blog NetworkManager replaced
dhcpcd as the suggested method for handling network interfaces.
I redid a search and came up with this nice long and heated thread about it:
https://raspberrypi.stackexchange.com/questions/37920/how-do-i-set-up-networking-wifi-static-ip-address-on-raspbian-raspberry-pi-os
Here is systemd-networkd static IP:
https://wiki.archlinux.org/title/systemd-networkd
And of course /etc/network/interfaces:
https://wiki.debian.org/NetworkConfiguration
In any event, you're operating a server (because you're running dnsmasq
on your Pi) therefore you should not be running DHCP on your server's
interfaces so there's no reason to involve dhcpcd at all[2]. Switch to
a known working method of assigning a static IP (either the interfaces
file, systemd-networkd, or NetworkManager) and you will be far better
off in the long run.

[2] The only exception to this would be a Pi running as a router in
which case the WAN interface might likely use DHCP to obtain an IP from
the ISP/modem but otherwise DHCP should be disabled on anything but the
WAN interface if the router is also your internal DHCP server.

The official blog does not list using that method at all. Instead it
either points to using a systemd network file or through the
/etc/network/interfaces file.
If so, I have been unable to find it... Sorry for that.
Can you give the link?
