After an update to the game today I can not move in any direction or jump and all the cheats, god mode etc are disabled and you can’t re-enable them.
you likely can’t move bc you are very over encumbered, as the cheats will not work till the mod is updated and that takes time
I offloaded everything I had, still can’t move. So aggravating as I’m probably 90% done.
Hello! 
Movement issues are a bug in the game that has nothing to do with using the trainer. People who do not use any trainers on the game can also experience the same, and it affects every platform the game is available on, consoles included.

the play mod is the problem also. the game can only play only 10 sec then crash even without activating any mod. just only using the play on the wemod itself. when i’m started normally it doesn’t crash but my player got encumbered and cannot move
These are two separate issues.

Can’t move = This is a game bug, not related to the trainer. It’s likely you ran into this bug hours ago in your playthrough, and that the trainer “fixed” the bug for you when it was working.

Crashing = As you said the game was updated. Therefore, the trainer will also need to be updated. You’ll need to wait for this to happen, and you can see the update queue in the WeMod software by clicking the “Creator” tab.
