Hi SE Community!

Here are the first things you can try when you have a game problem :

1 - Restart the PC
+
*2 - Verify the game files with Steam.

Or

*3 - *Delete the CFG file. (steps below / go to *)

Or

*4 - Delete the content of the ShaderCache folders. (that one fixed loading problems)

_____________________________________

*2 = How to Verify integrity of game cache:

- Right click on Space Engineers in your Steam Library.
- Go to properties.
- Go to LOCAL FILES tab.
- Click Verify integrity of game cache
- When done try the game.
___________

*3 = Hit the Windows key + R = opens the "Run" window to type in :
%appdata%\SpaceEngineers

> Goes to the SpaceEngineers folder
C: users / your username / appdata / roaming / spaceengineers

>> then *delete the ''SpaceEngineers.cfg'' file and try the game.

*delete = Doing so resets all SE options and controls to default, a new cfg file will be created.

____________

*4 = ShaderCache folders are in appdata SE, same place above ^
C: users / your username / appdata / roaming / spaceengineers / ShaderCache
+
May also delete the content of the other ShaderCache folder in the Steam folder :
C:\Program Files (x86)\Steam\steamapps\common\SpaceEngineers\Content\ShaderCache




=> install latest C++ (x64: vc_redist.x64.exe) from the MIcrosoft Website :
https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

From NikolasMarch :
"They need 2 VC++, 2013 and the latest 2015-2019"




From Dev filcon :
You can try to delete all files in this directory - %AppData%\SpaceEngineers\Promo\

From Smokey :
Right click space engineers in the game list, go to set launch options and put in the box
-skipintro
Click ok, close pop up box and no more intro movie upon loading

From Rox :
go to <path>\steamapps\common\SpaceEngineers\Content and rename the 'Videos' directory




1 - Select your save.
2 - Click the "Save as" button on the left.
3 - Change the save name to create a *copy.
4 - Withdraw or add one Mod at a time in the copy.

5 - Report to the Mod author (on WS item page) when broken Mod found so he can fix/update his Mod, always very kind to let them know.

*copy
Never test with your original save, better create a copy and fix the original save when solution found in the copy, this way you will not mess up your save.

1 - Backup Saves and Blueprints, copy/paste to USB storage key or else.
Saves and Blueprints are here :
Hit the Windows key + R and type in : %appdata%\SpaceEngineers
Goes to the SpaceEngineers folder
C: users / your username / appdata / roaming / spaceengineers

2 - Uninstall the game with Steam.
3 - Delete all remaining SE folders/files in the Steam folder.
4 - Delete all remaining SE folders/files in the appdata SE on your C: Drive.
5 - Restart PC.
6 - Install Space Engineers game.

7 - Create a new No Mods/No Plugins world, load to create a new Blueprint (a few blocks will do), save and exit the world.

-> We do so (#7 above) to have the Saves and Bluepints folders created new.

Online World saves goes here :
C:\Users\ (your username) \AppData\Roaming\SpaceEngineers\Saves\ (Your Steam ID)
Local Blueprints goes here :
C:\Users\ (your username) \AppData\Roaming\SpaceEngineers\Blueprints\local



Some members were not able to join MP worlds and here is what they did to fix :

1 - The problem was caused by router MTU being set to 1400 to my ISP gateway. Changing the MTU to 1500 fixed the problem.
MTU = Maximum Transmission Unit

2 - Turn off ASUS' ROG GameFirst, that app got reported preventing members to play MP.

3 - Also one member was stuck in space and could not see the respawn screen, he switched to Wifi to fix.
(switch to direct wire connected to home router if you already use Wifi)

NOTE
One player reported that "CloudFlare WARP" and "Network optimizers" can give problems on servers, like can't see HUD.



We are finding that some players loading into areas with a large amount of blocks or voxel deformation are getting CTD. To get around this, they need to turn down their graphics to minimum until they have loaded in. After this they can safely turn them back up.
