Steps to reproduce the behavior:

1. Go to 'Geräte'
2. Click on '+' to create new device
3. Fill out input mask
4. No furher configuration dialog appears

Expected behavior
After pressing button no input mask appears to configure the new alias device. Selecting specific icons are also not possible.

Screenshots & Logfiles

Versions:

• Adapter version: <1.0.12>
• JS-Controller version: <4.0.23>
• Node version: <16.16.0>
• Operating system: bullseye-32bit

Additional context
After reinstalling the Device Adapter, the following error message is displayed:

INFO: Directory "/opt/iobroker/node_modules/iobroker.devices/www" was not found! Nothing was uploaded or deleted.

When I look via ssh in the /opt//iobroker/node_modules/iobroker.devices folder, the "www" folder does not exist.
