Why the F are the pings in this small network so screwed up?

I recently connected an Aruba WiFi Bridge 501, linked to an L2 HP switch, which leads to my laptop, to my company network to test a couple of things.

After initial setup and verifying that the Bridge is connected and working as intended, i did some ping checks to test the other devices, and here is where i dont get how this is possible. Both the WiFi Bridge and Switch are out-of-the-box with minimal configuration.

Here is a small michelangelo to show what pings work and which dont (it looks as confusing as it is to me)

both laptops and the management interfaces (that were used to ping) on switch and router are in the 192.168.169.128/25 subnet. the wifi bridge's mgmt interface is configured via DHCP by a DHCP server in the company network. DHCP does currently not work on the switch/laptop behind the bridge.

my main confusion right now is why the switch cannot ping ANYTHING at all, even though the connection from laptop to laptop or laptop to wifi bridge works.

The Switch is an HPE OfficeConnect 1820, the WiFi Bridge an Aruba WiFi Bridge 501. I am so incredibly confused, i hope anyone even reads this. Also hope this is the right sub for this.
