Can't set Wireless LAN (raspi-config - Pi4B)

I tried in two fresh installs and after activation, basic configuration and enabling SSH, when I use raspi-config to set my wifi I get the following error:

Traceback (most recent call last): File "/usr/sbin/netplan", line 23, in <module> netplan.main() File "/usr/share/netplan/netplan/cli/core.py", line 50, in main self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 241, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 50, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 241, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 72, in command_set libnetplan.create_yaml_patch(yaml_path, value, tmp) File "/usr/share/netplan/netplan/libnetplan.py", line 501, in create_yaml_patch _checked_lib_call(lib.netplan_util_create_yaml_patch, File "/usr/share/netplan/netplan/libnetplan.py", line 79, in _checked_lib_call raise LibNetplanException(err.contents.message.decode('utf-8')) netplan.libnetplan.LibNetplanException: Error parsing YAML: did not find expected ',' or '}'

And no wifi connection.
