Log in and join server, see my character and then game crashes over and over. Reinstalled, repaired, etc... any ideas?

It's hard to say why this might happen, write to support. I had it crash three times when I climbed into a truck. And I tried to get out, it got stuck between the houses in the city. And while I was trying to steer out, the game crashed. But then I just gave up on it.

No guarantees, but maybe try this workaround: Close the game (if open). Go to the installation folder ...\Once Human\Documents. Delete the following folders: baking_ppk, db_py3, and patch_ppk. Settings will be reset, and shaders and other files will be regenerated. After this, you should be able to get back on the server again.

I'm copying my reply in a different thread.

I had a similar issue as well. Turns out Once Human uses quite large memory, which it will instead uses Virtual Memory if you don't have large enough RAM. Make sure you have enough disk space (default in C) for the Virtual memory to allocate. In my case (PC with 16 GB RAM), it uses additional 5GB of virtual memory in C.

TLDR: Make sure you have enough disk space in C (at least ~5GB of free space)
