Hello Nicholas,
I guess the Maintainer would need more information about this issue.
A first step might be to provide a "strace" of a mtink startup.
Therefore please install the packages: bsdutils strace
Then execute following line in a terminal:
script -c "LANG=C strace -f mtink" -a "mtink-strace_$(date +%Y-%m-%d_%H-%M-%S).log"
This will create a file like mtink-strace_2022-12-11_14-16-46.log
Maybe you could compress this file and attach it to your answer to this mail?
(Please use the "reply all", to have the bug in CC in your answer.)
Kind regards,
Bernhard
