markdown-link-check hang and can't timeout or exit with error

[wuwentao]

I'm not sure with this error debug , there is no any error or timeout or exit, it will hang more than 10-20 minutes, not every md file can't work, hang log as below:

any suggestion or debug info to check what's wrong with it ?
not every document in this mode, it also can works in some md file as below:

this md file should works well as below, after I use CTRL+C to force quit the error md file and rerun with another md file:

found the root cause, this markdown have a 4+GB download link for [MATLAB_Runtime_R2023a_win64.zip]
so markdown-link-check will download the full file and our network speed is too slow, it will required at least 30+ minutes to finish the download job, so it always hang and can't return or print any info before it download the zip file.

also manual checked with wget to directly download this file, the network should be ok, but there is a http 302 redirect, so wget can follow it, result as below:

/usr/local/bin/markdown-link-check -a 301,302 -r -v -p xxx.md
