I can suggest trying these actions: 1. See if ACU boots up without my preset, maybe there could be memory spike when loading it for the first time and it's better to let ReShade load on its own at first and then add my preset 2. If you downloaded regular ReShade version, try the one with full addon support. It's the version I use though not enabling any addons, still maybe there's a difference resulting in game crash 3. Lastly try using older ReShade version https://reshade.me/downloads/ReShade_Setup_5.9.2.exe. Some other ReShade author mentioned that ACU can crash with other versions, though I personally don't experience any problems using latest one, still might be worth a try UPD: Did fresh installation of latest ReShade version with addon support, no crash on boot. If the steps above don't help, then can only suggest checking tutorials on YouTube regarding ReShade crashes
