Trainer in single player?

How can i get trainer to work in single player “invoke-level” I have put the trainer in the plugin folder and it works great on servers but not working in single player

Are you able to atleast move in invoke-levelloaded maps? For me, invoke-levelloaded maps didnt work. The maps loaded but the player was stuck in a T pose. I had to host a server and connect to it to access the map. The trainer works in the server connected instance, but not in the singleplayer.

Same for me, Stuck in t pose and cannot move. servers work fine
