FWIW, I was having this exact same problem and I was able to fix it by increasing the amount of memory available to Lua (the underlying scripting engine). If you want to as well, you can edit the following file (your location may be slightly different):
“C:\Program Files (x86)\Steam\steamapps\common\Warhammer 40,000 DARKTIDE\launcher\Launcher.exe.config”
Search for <setting name="ExeArgs" serializeAs="String">
. I doubled the memory (to 2G) so it now looks like this:
<setting name="ExeArgs" serializeAs="String">
<value>--bundle-dir ../bundle --ini settings --lua-heap-mb-size 2048</value>
</setting>
To be clear, I believe this is different from what OP is talking about. I’ve also experienced that and I’ll be looking for logs the next time it happens.
