suspicious internet connection at startup

Hi, i have noticed a blocked connection attempt on my firewall. This takes place from the start of coi and is repeated permanently.
IPv4 - UDP -> 3.130.193.195:12201
(195.193.130.3.in-addr.arpa name = ec2-3-130-193-195.us-east-2.compute.amazonaws.com.)
I have an OPNsense Firewall OS on real hardware and is strictly configured (default any-any deny). I didn't find anything about the port activations you needed. Standard ports such as HTTP/HTTPS are open.
Can you tell me what it is and why?

check if it still occurs when the "Send error reports" option is disabled

This is anonymous error reporting, when "Send error reports" is unchecked this should not occurr. If it does, please let me know.

If you are curious what is being sent, this is an example message:
