Troubleshooting solutions:
#1. Make sure your MMD folder is NOT in "Program Files", "Program Files (x86)", "ProgramData", "Windows", or any other folders that are OS protected. X3
Programs/Softwares that are in these locations may need to be run with ADMIN Credentials for them to work properly. >w<
Examples paths for safe folders/files: "C:\Users\NameHereExample\Documents", "C:\Users\NameHereExample\Desktop", or secondary HDDs/SSDs should be fine. :3

#2. R U using Win11? ?w?
If so, copy UR MMD to a FlashDrive or another HDD and then open it up on another computer with Win10 or older if possible. ^w^
If you don't have an extra PC to test then either downgrade your PC to windows 10 or older, or move on to other solution steps.
If the same problem happens then it's not Win11's fault. >w<

#3. Last resort option, RESET MMD! XwX
Move all model and MME (do not move the raycast folder) folder/s out of the errored MMD folder to documents.>w>
Delete the errored MMD folder and redownload MMD and MME from https://learnmmd.com/downloads/ ;
Then re-download the latest MME Raycast from https://github.com/ray-cast/ray-mmd/releases ;
Then try it again (make sure U pay attention to the "#1." above as well when redownloading and unpacking the MMD program). ^w^

#4. If the problem still persists after checking and/or doing all #s steps then it's either the Windows OS itself or a Hardware incompatibility (A.K.A UR own computer), in which case the only solution for that is to go buy a new computer.
