Repetitive issue with GPS at specific location with tall buildings

Fenix 5X, software 22.20, GPS 2.70.

The issue is repetitive, ie several course runs showing the same issue at the same spot with tall buildings on the left side and a pool of water on the right. Plenty of line of sight to sky. I wonder whether there is a GPS blocker somewhere.

Attached 2 runs 2020-10 and 2021-06

Although possible more likely accidental GPS interference, interference from some other network running similar freq (maybe over powered), multi path interference specific to the set of buildings etc etc. You could try changing the constellation settings in the watch and see if that makes a difference (GPS, Galileo, Glonass)

My default set-ups is GPS + Galileo. I don't think Glonass instead of Galileo should make a difference but have not tried
