Unable to access internet after installing Pi-hole

Expected Behaviour:

RPI bridge eth0 and wlan1to br0(192.168.1.1) with eth0(192.168.100.xx) connected to WAN with Pi-hole running and blocking ads

Actual Behaviour:

Fresh install with the follow command to bridge eth0 and wlan1to br0(192.168.1.1) with eth0(192.168.100.xx) connected to WAN and connected devices have access to internet

Followed by pihole installation which results in connected devices with no access to internet and the following error message appear on pihole diagnosis page
"FTL failed to start due to cannot open or create lease file
/var.lib/misc/dnsmasq.leases;Permission denied"

the following were run followed by pi-hole installation

sudo apt install hostapd
sudo systemctl unmask hostapd
sudo systemctl enable hostapd

sudo nano /etc/systemd/network/bridge-br0.netdev

sudo nano /etc/systemd/network/br0-member-eth0.network

sudo nano /etc/dnsmasq.conf

domain=wlan # Local wireless DNS domain
address=/gw.wlan/192.168.1.1

After installing pihole

dnsmasq.conf is left with below code

conf-dir=/etc/dnsmasq.d

and i am unable to access even192.168.1.1/admin
after adding back my bridge setting to dnsmasq.conf, i am able to access192.168.1.1/admin

conf-dir=/etc/dnsmasq.d

interface=br0 # Listening interface
dhcp-range=192.168.1.50,192.168.1.99,255.255.255.0,24h
# Pool of IP addresses served via DHCP
domain=wlan # Local wireless DNS domain
address=/gw.wlan/192.168.1.1
# Alias for this router

i tried

sudo service dnsmasq stop
sudo service dnsmasq disable
sudo service pihole-FTL restart

which failed to work so i removed dnsmasq which gives the same result

sudo apt-get remove dnsmasq 
sudo service pihole-FTL restart

i am able to ping 8.8.8.8 and 8.8.4.4
inside dnsmasq.leases there are mac addresses and IP of connected devices

anyone knows any solution to this issue?

pihole-FTL has dnsmasq builtin since v4, which is the reason it failed to start when your manually installed dnsmasq was running and created a lease file that the pihole user was not permitted to write to.

But further debugging is at best done by someone with access to your debug upload.

Please generate a fresh debug log and upload the new token. Your old log has expired.

here is the new log https://tricorder.pi-hole.net/zeg4ezupib

i managed to somehow enable pi-hole however when raspberry pi is restarted, it takes a few minutes for my other devices to able to connect to the internet.
during the unable to connect to internet period, dhcp is active and my device is allocated with an ip address and i am able to ping 216.58.220.131 but not address like www.google.com
