@[3TON] Dagor-Naur: I'm using the same workshop file, and unable to reproduce your issue.

First try and check SRHK game file integrity.

Second clear the mod in case for some odd ball reason it's corrupted on your system. I've noticed even an unsub from the mod still leaves it in the workshop mods folder.

Search for the below directory+file and clear the folder, unsub/resub, and launch the game. It'll auto download the mod again.

"\Steam\userdata\33050299\346940\local\ugc\1484994003\contentpacks\5b770c4a6133356c01005f91-Combat Test Arena.cpz".

Also there multiple log files. Check if they mention the crash issue.
"\Steam\steamapps\common\Shadowrun Hong Kong\DumpBox\*LongAnalysis.txt"
"\Steam\steamapps\common\Shadowrun Hong Kong\steamwrap.log"
