6.4 ctd before battle Nothing helps

[Kuosa]

Hi, I hope this is still active. After a few years I wanted to start playing again but for 2 days I'm not able to. I have done everything suggested in this Forum and that of Steam: multiple re-installs, bugfix, rbai, everything up to disabling daylight savings... I know I installed it right, followed every instruction and suggestion and fix and before any battle it just crashes always with the unsp. error. Pls help.

Unfortunately, your log doesn't say anytrhing.

Have a look here in order to get a more detailed one. With that, your log might be quite long. So if you post it here again, please do it as an attached doc.

Meanwhile, what's your era, early or late?
Does it happen for all factions or just for one or several specific one?
