Any ideas how to fix this without reinstalling Pfsense from zero?

You can edit the config and remove the disks widget from the dashboard since that's what appears to be triggering the error.

What disks do you have?

Thx
I have 2x SSDs in RAID1 ZFS array (if I remember some crucial 64GB).
How can I do what. Last time i do sth in PFsense was few years ago and don't remember anything :)

Safest way is to backup the config from https://<your-firewall-ip>/diag_backup.php. Edit it then restore the config. That way pfSense will refuse to import it of you have typo'd something.

Look in the config for the widgets section like:

	<widgets>
		<sequence>system_information:col1:open:0,disks:col1:open,interfaces:col2:open:0,services_status:col2:open:0,gateways:col2:open:0,snort_alerts:col2:open:0</sequence>
		<period>10</period>
		<gateways-0>
			<descr><![CDATA[Gateways]]></descr>
			<display_type>both_ip</display_type>
			<gatewaysfilter>WAN_DHCP6</gatewaysfilter>
		</gateways-0>
	</widgets>

Remove the disks widget. So there I would remove: disks:col1:open,

But the widget should be fine with just a ZFS mirror. What do you see from?:
zfs list; mount -p; geom disk list;
