Pritunl breaks systemd-resolved

Running Pritunl Client v1.3.3484.2 on Ubuntu 22.04.

$ nslookup localhost
Server:         127.0.0.53
Address:        127.0.0.53#53

$ pritunl-client start efdtqldtiq1lrzll

$ nslookup localhost
;; communications error to 127.0.0.53#53: timed out
;; communications error to 127.0.0.53#53: timed out
;; communications error to 127.0.0.53#53: timed out
;; no servers could be reached

How to debug this further?

I can’t reproduce this issue on Ubuntu 22.04 with the CLI client.
