there has been an issue that ive just recently had with my minecraft launcher where it doesn't show any installations, neither does it let me run the game because when i press play on the launcher the warning sign in the top right of the launcher says "Sorry, unable to start Minecraft. Please check your configurations."

i have tried to reinstall and repair minecraft from the minecraftinstaller but that hasn't helped. im not sure if this is because of my computer but let me know if this issue can be resolved
