It’s more likely a route issue. Assuming you changed internet providers, each provider has their own combination of public/private internet routes. This can lead to getting a bad route. Another thing that can change, which you should check, is your DNS provider.
Your internet provider has a default DNS. It’s possible it’s picking a particularly bad Qobuz access point. You can and should use a private and encrypted DNS instead. You set this up in your router (hopefully you are not using theirs) and should consider any of:
Top public DNS providers offer improved speed, security, and reliability over default ISP settings. Top choices include
Cloudflare (1.1.1.1) for speed, Google (8.8.8.8) for reliability, Quad9 (9.9.9.9) for security, and OpenDNS (208.67.222.222)
(those comments are from Google Gemini, treat with a grain of salt, but Quad9 and OpenDNS are two I recommend.
Lastly, it's worth looking around for Qobuz users on the same internet provider you are using to see if there were similar issues and possible workarounds. Honestly, routes have to be really bad to get bad audio streaming, but it does happen.
