Rimworld does not load after 'Initialization'

You can have a look at these threads, they offer various information about how to get system information, find logs, and so on:

[HowTo] Find system information

Difficulty: ★☆☆☆☆ Rather than providing the commercial reference of a computer or piece of hardware, it is usually better to directly ask the system to describe itself. On top of saving time to everyone, this also often provides more details, including something specific to the running system. Below is a (not exhaustive) list of commands for retrieving system information. If you don’t know how to use those commands, or how to provide them to support, see: [HowTo] Use the terminal / TTY …

[HowTo] Request support

Difficulty: ★☆☆☆☆ Strong of its many members, the Manjaro support forum can provide you help whenever you have an issue with your Manjaro installation. But in order to work efficiently, we shall also ask you to follow three major points. Provide context Simply signaling an issue is rarely enough to understand how it occurred. It is thus important to provide details on how it happened: Detail prior actions leading to the issue. List solutions and guides you already tried, with links whene…

• What I would recommend to troubleshoot, use the normal Steam from the repositories, no other version.
• Verify the game files
• Clear your Proton prefix for this game (basically delete the WINE/Proton prefix folder corresponding to the game, located by default at ~/.local/share/Steam/steamapps/compatdata/XXX where XXX is the AppID of the game, in our case, Rimworld is 294100). If the Proton prefix contains savegames (and the game does not support Steam Cloud Save) or other files you want to keep to transfer later to a working Proton prefix, simply RENAME the folder instead of deleting it.
• Make sure you have the latest Proton version 9 selected in Steam Settings under Compatibility (and make sure you do not force another version in the game Properties under Compatibility too).
• Make sure your system is up to date sudo pacman -Syu and you’re using recent LTS kernel.
• Reboot if system was updated (sometimes, even when nothing happened, Steam can fail to create the games window, I don’t know why, it happened to me, just reboot, when in doubt), and try again starting Steam from terminal to get direct output, and logging Proton by adding this Launch Option in the game Properties PROTON_LOG=1 %command% so a log file is created in your Home folder (very verbose and maybe too complicated to read but sometiumes has good info)

Start from here, provide most information possible.
