dnsmasq is not resolving protonmail.ch, met.no unless I set
Code:
server=/met.no/1.1.1.1
in additional options, along with other random domains.
I switched my computer dns to 1.1.1.1 and everything appears to work properly, I tried various ddwrt provided encrypted dns resolvers and it occurs every time.

Screenshots of applicable configuration information from Setup -> Basic Setup and Services -> Services as well as applicable Additional Dnsmasq options may help troubleshoot the issue.

You're encrypting DNS but using all-servers. Why? Are you also ignoring WAN DNS (which is an applicable config item... but no screenshot...)?

Yeah sorry about that, I am using ignore WAN dns. I noticed after restarting the router different websites are getting affected now.
UPDATE: protonmail still isn't loading at all, trying to load some websites returns DNS_PROBE_FINISHED_NXDOMAIN, and shortly after the website loads on chrome.

UPDATE 2: Disabling DNSSEC caching and DNSSEC validation fixed all my issues, still getting ERR_NAME_NOT_RESOLVED for a short second before the site loads.

Because you are using all-servers. Try re-enabling dnssec stuff and removing all addtional configs...

Didn't make a difference unfortunately, the only thing that worked is using static DNS settings or ISP WAN DNS without dnsmasq.

I did a full reset, flashed stock NETGEAR Genie software and rolled back to latest ddwrt, seems that issues are gone for now...

"Forced DNS redirection" is also helpful and probably where it was balking; but if you are going to use additional configs, there are plenty of examples of what works and what does not. The all-servers directive may override other settings. I would also have to back-track as to where in the development process that build is to see if there was something I overlooked, but I don't think I have...
