Connecting to Ubuntu using ssh over Ethernet

I have given static IP 192.168.137.20 with net mask 255.255.255.0 to my windows laptop port:

Then I connected my rasberry pi (which runs Ubuntu 20.04) using USB and ran following command to also give it a static IP and netmaskputtsdsdsd:

# sudo ifconfig eth0 192.168.137.50 netmask 255.255.255.0

Now both of them should be on same network. I connected my raspberry pi to my laptop using ethernet port and tried to connect to it over ssh using putty. Earlier it used to work with same procedure, but now it does not. In fact I am not able to ping each device from other device over Ethernet. I tried:

ping 192.168.137.50

on laptop and

ping 192.168.137.20

on raspberry pi. Both say Destination Host Unreachable.

Now only thing I recall could be an issue is some config file. I recall modifying /etc/resolv.conf when I was able to connect over ssh, but not able to ping google. However, I changed it back, below is how it currently looks like:

# cat /etc/resolv.conf
# Generated by resolvconf
nameserver 127.0.0.1

Am I missing anything?

PS:

The ifconfig shows following on rasberry pi:

eth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
    inet 192.168.137.50  netmask 255.255.255.0  broadcast 192.168.137.255

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
