Description of issue:
When I try to grab a Squid Game series release which cannot be parsed by Sonarr, I get a red cloud and download doesn’t start. With other series everything is working fine

A single line error is not helpful for debugging at all.

Please provide logs as the wiki entry the template links to indicates
https://wiki.servarr.com/sonarr/troubleshooting#logging-and-log-files

Trace log:
https://hastebin.com/sigeduyagu.yaml

What’s the release name? Seems it’s not parseable at all and sonarr is choking on it.

Игра в кальмара / Ojingeo geim / Squid Game / Сезон: 1 / [9 из 9] (Хван Дон-хёк / Hwang Dong-hyeok) [2021, Южная Корея, триллер, драма, HEVC, HDR, WEB-DL 1080p] MVO (HDRezka Studio) + Original (Kor) + Eng + Sub (Rus, Eng, Kor)

Sonarr actually sees it like that (I am using Jackett):
