Upgraded earlier to Beta release 22.05.b.20220531.0600 and now to RC release 22.05.r.20220604.1403.
Problem still persists on both versions.
EDIT:
Seems that the problem appears if you have 2 (or more) System Information widgets with different contents on the Dashboard.
EDIT 2:
Looks like it's specifically caused by the "CPU Type", "Uptime" and "Current Date/Time" fields, as log as all of them are visible in all System Information widgets, everything is ok. If one or all of those fields are hidden in one of the System Information widget, then they start to act up.
