I am using vpn to open ports since my isp blocks.I found only tcp ports are opening.
I have tried 3 different vpns(pia,cryptic,airvpn) with same result.
I tried allowing port through firewall and turning firewall off completely.
I also tried using another laptop.Both of my laptops have windows 10.
I even tried changing isp but same result.
Any help would be appreciated.

What do you mean "opening" UDP ports. By default traffic you send from a UDP port is allowed to return. That is a standard nat function. The port number may be translated by NAT but whatever port is used will be allowed to come back and be translated back. This the standard way nat works.

If you mean you have some UDP port that you want a external device to send traffic to without traffic being send out first then you need to have port forwarding rules set. If the ISP blocks your ability to port forward certain ports a simple VPN will not fix that. You can not do port forwarding on a VPN connection since you have no control of the device doing the NAT. Although there might be a VPN service that allows you a fixed IP and...

Although there might be a VPN service that allows you a fixed IP and the ability to port foward the way most people do this is to buy a VPS service that has a fixed ip address. You then run a router function on the VPS and do this all yourself.
