If you can't access your server and your router's web interface, that's a subnetting/DHCP allocation issue. Nothing to do with Pi-Hole.
For reference, there's 2 ways to allocate static addresses to devices:
"Skill issue bro" /s
First thought: Is your PiHole's static IP within the range of addresses your DHCP server hands out?
Do you run your PiHole on top of Docker? There's an issue with docker and Raspberry Pis which makes the network crap out periodically. So if your PuHole becomes unavailable until you restart your Pi it might be this:
https://github.com/raspberrypi/linux/issues/4092/
Solution is to add "denyinterfaces veth*" to the dhcpd.conf
My first thought on this was immediately "did you also reserve that static IP address on your router to make sure it remains assigned". From what I've read that does seem to be the issue, so that's a little validating.
Taking a look at your Pihole logs is going to be helpful. Also knowing what kind of device is running the Pihole software may also help.
I had Pihole running on a raspberry pi 3 years ago, and I had pretty consistent issues. I've run it on other hardware since without a problem.
It could be an issue with the SD card, if you're using a raspberry pi. I've also read that the log file can grow large enough to cause issues with your Pihole instance.
So there are a number of possibilities.
I would HIGHLY recommend that for something as essential as DNS, you should be running it on its own hardware. Considering, as you’ve experienced, that any issues result in a complete loss of normal access to the internet.
You can run pihole on something as small as a Raspberry Pi zero w, then just set it with a static IP and forget about it.
Considering you said you’re currently using WSL I suspect there is an extra layer of networking bullshit that is breaking your routing. If you haven’t already looked at this document, it might have the information you need https://learn.microsoft.com/en-us/windows/wsl/networking#accessing-windows-networking-apps-from-linux-host-ip
But for the sake of stable DNS services you will thank yourself for just getting a dedicated device of any power level to ONLY handle DNS.
Are you assigning the static address on your pi, or are you assigning a static address on the router?
Your static IP probably isn't set on the router

I had similar issues when SLAAC wasn't properly configured for my network. Every however many days my ISP forced a modem reboot and if the delegated prefix happened to change I'd start having pihole problems. I finally tracked that down, made sure SLAAC was working everywhere and assigned my pihole container a SLAAC token so its address relative to everything else on the network didn't change and I'm good to go. These days the pihole is always ...253 and ::253.
