Just wanted to confirm that you have LTE internet … the high Ping values on your Speedtest results seem to indicate you have a LTE internet service.
If that’s the case then you’re maybe faced with the same problem as
Wyze OG Cameras Stuck on version 1.1.0.85 - Cameras - Wyze Forum
where the issue was high latency on a Verizon internet service. In this case the user was able to use a friend with fiber/cable internet to complete the firmware update and then set up on their own network.
