Just upgraded to the latest version of STM32Cube for VS Code extension (3.6.4) and now the extension stopped to work. I've tried reinstalling the extension pack several times. Every time after the bundle was installed an error show up saying "An error occurred while synchronizing metadata. Please try run "STM32Cube: Install prerequisite bundle" and "STM32Cube: Synchronize pack list". Or work offline."
Running "STM32Cube: Install prerequisite bundle" from the VS Code command palette will result in a message saying "No STM32Cube bundle to install", subsequently running "STM32Cube: Synchronize pack list" will return the original metadata synchronization error.
I checked my HOME/Library/"Application Support"/stmcube/ directory, the bundle/ folder seems to contain what I expected, things like cmake, gnu-gdb-for-stm32 or the stink-gdbserver, etc. However, the packs/ folder is empty, not sure if that's the problem.
I checked the output log of STM32Cube Core and found the following:
```
[Info] 'cube pack sync' exited with signal null [1]
[Error] Failed to synchronize PDSC metadata: Syncing metadata information /Users/poshengcheng/Library/Application Support/stm32cube/packs

Syncing online metadata information /Users/poshengcheng/Library/Application Support/stm32cube/packs
Error during metadata sync: Error: Unexpected close tag

```
Additionally, after I selected a MCU device in "Setup STM32Cube Project(s)", downloading the supporting packs for the specified device always fails. The following message is from the output log of STM32Cube CMake Build:
```

2025-10-17 22:58:48.071 [Error] Failed to download pack 'STMicroelectronics.stm32l4xx_dfp.1.1.0'. Please check your setup and try again (via command line 'cube pack install <pack_id>' or via command palette 'STM32Cube: Restore STM32Cube CMake projects configuration')
```
So far I've only been able to build the project but attempts to debug have failed since the stm32cube doesn't seem to be able to setup the project with the selected device.
