With config:

upstream:
  - "https://[2620:fe::fe:11]/dns-query"
  - "https://[2620:fe::11]/dns-query"

v0.64.0 no longer starts:

Jan 29 08:36:39  dnsproxy[19719]: 2024/01/29 08:36:39 [fatal] error while parsing upstreams configuration: parsing error at index 0: cannot prepare the upstream: invalid address [2620:fe::fe:11]: bad hostname "[2620:fe::fe:11]": bad top-level domain name label "[2620:fe::fe:11]": bad top-level domain name label rune '['

It works in v0.63.1

Thank you for your report. Fixed in v0.64.1.

It works, thanks for the fix!
Could you please log the upstreams at startup? It would be very useful to confirm such cases when using a mix of ipv4 and ipv6. I asked for it a while back, like 2 years ago ... #200
