Arduino IDE 2.0 with Atmel ICE Failed to launch OpenOCD GDB Server

Development Tools Uploading

I'm running on Windows 10 and have used Microchip Studio previously with my proprietary SAMD21-based board.
Since Arduino changes have broken the import function in Microchip Studio (and the import was never that smooth anyway) I wish to use the new Arduino IDE 2.0.
My IDE version is 2.0.0-rc5, CLI Version 0.21.0.

However, I get the following error: Failed to launch OpenOCD GDB Server: Timeout.

Any ideas as to what could be wrong? Could it be Firewall related?

Yes. Does it work if you turn the firewall off?

There will be a delay of a week or so before I can try that.
I noticed that rules had been set up for the IDE in the Windows firewall.
Seems odd that nobody else has run into the same problem if that is the issue.
Anyway, I'll update when I get a chance to investigate further.

I doubt that the default firewall rules will pose problems but if you changed anything this might be the cause of your problems.

I disabled the Windows firewall - no change.
No notifications from either Windows or Malwarebytes.
What exactly does ocd_bouncer do and is there a way to get better error reporting?

Don't forget you're using a pre-release software so there might be bugs.

The On-Chip-Debugger is a new feature of the 2.x version of the IDE. It's used for debugging but I haven't tried it yet. At least for the UNO you need additional hardware to use it.
