Make sure your launcher is the latest version (you can check that by looking at the filesize, latest one is 4123KB), if it's not download it from here: https://cdn.plutonium.pw/updater/plutonium.exe.
Download this https://drive.google.com/u/0/uc?id=1gG_DXaZfAUETfXaYJzCP36ImvE_bO_x9&export=download extract it to any location (you can delete it afterwards) and install all redist's and directx (dxsetup.exe in the directx folder).
run the launcher as admin.
make sure the file path to the game files does not contain special characters.
If it still doesn't work:
go to windows security -> app & browser control -> exploit protection -> exploit protection settings
turn off "randomize memory allocations (Bottom-up ASLR)"

If it still doesn't work follow this guide to repair your installation:

If it still doesn't work i'm out of ideas.
