No internet connection within WSL while OpenVPN is installed

[thirdcoffee]

Windows Build Number

10.0.19042.928

WSL Version

• WSL 2
• WSL 1

Kernel Version

5.4.72

Distro Version

Ubuntu 20.04

Other Software

OpenVPN 11.23.0.0 on Windows

Repro Steps

Install WSL2.
Install OpenVPN. (Disable it in Autostart & disable the OpenVPN service - tried to fix it by doing this).
Try getting an internet connection within WSL e.g. ping a domain or IP.

Expected Behavior

Normal WSL with internet connection.

Actual Behavior

e.g. I can't ping either ip addresses like 8.8.8.8 (From 172.28.209.182 icmp_seq=1 Destination Host Unreachable) or domains like google.com.

I never had a problem with the internet connection in my WSL install until I installed the OpenVPN client we're required to use for university. As stated before I disabled it in autostart & stopped the service, still not working.

I'm aware there are other issues with similiar problems with Cisco AnyConnect etc. on here.
I tried some solutions, nothing worked. I'm quite desperate now.
