gdb crash after breakpoint (VSCode)

Using the latest GNU Arm Embedded Toolchain (10.3-2021.07) available from here:

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

With a Segger J-Link BASE, when I set a breakpoint, the breakpoint hits, but
there is no way for me to control/resume program execution, and the debugger
crashes - as shown in the attached screenshot.

This issue does not occur with GNU Arm Embedded Toolchain 9-2020-q2-update.

Other details of my environment:
 - Windows 10 version 21H1 (OS Build 19043.1110)
 - J-Link tools V7.52c (latest stable)
 - Visual Studio Code (VSCode) 1.59.0 (user setup), with Cortex-Debug plugin
v0.3.13 Preview
