Hey everyone! I'm running into a problem with the AWS VPN Client version 5.2.1 crashing as soon as I try to launch it on the latest macOS 26 Developer Beta 6. I've already uninstalled and reinstalled the app, plus restarted my Mac, but it just won't run. I'm curious if anyone else is experiencing this issue on this macOS beta version or if there are any known workarounds or fixes.
Here's a bit from the error logs that might help:
- Error Message: System.Reflection.TargetInvocationException
- OS: macOS 26 Developer Beta 6
- AWS VPN Client Version: 5.2.1
Any suggestions would be greatly appreciated! Thanks!

I've had the same issue, but I found that downloading an older version of the AWS VPN Client (version 4.1.0) resolved it for me. You can find it in AWS's release notes here: [Link](https://docs.aws.amazon.com/vpn/latest/clientvpn-user/client-vpn-connect-macos-release-notes.html). Give it a shot!
It sounds like this crash is likely due to compatibility issues with the macOS 26 beta. Normally, AWS VPN updates are slow to catch up with beta versions of macOS since they focus on stable releases. Here are some quick workarounds you might try:
1. Roll back to the last stable version of macOS or use a non-beta partition when you need VPN access.
2. If you have the capability, you could run the Windows version of the AWS VPN Client in a virtual machine like Parallels or UTM.
3. Alternatively, consider configuring your AWS VPN endpoint manually with something like OpenVPN or strongSwan. It might be a bit clunkier, but it can bypass the AWS client altogether.
Also, don't forget to reach out to AWS Support and share your issue in the AWS re:Post forum. They often pick up on dev beta issues quicker when they see multiple reports.

Awesome, I just tried version 4.1.0 too, and it worked perfectly! Thanks for the tip!
