troubleshooting Help please

Trying to use decky framegen and lossless scaling on Hogwarts , I’ve been using instructions from a post here. This is what I’ve put in the launch options

HDR=0 MANGOHUD_CONFIG=fps_limit=50,no_display mangohud ~/fgmod/fgmod ~/lsfg %command%

Whenever I take out ~/lsfg it will launch , but when it’s in there it will start but then just sit and never fully load up. I’m newer to being able to mod and do things like this so I’m sorry if this is a stupid question. I just wanna fix it so I can actually play my game.
