First thing you want to do is check if your Minecraft launcher located at C:\Program Files (x86)\Minecraft Launcher, if not - find where your minecraft launcher is located and drag it into C:\Program Files (x86)\, after you've done it you should rename the minecraft folder to "Minecraft Launcher"
If that didn't help - download this archive https://www.mediafire.com/file/jw14jsdtytuof20/runtime.rar/file and put all 3 folders inside C:\Program Files (x86)\Minecraft Launcher\runtime\ folder
Doing all those steps will most likely fix this issue, hope that helped!
