I have this problem for so long now. Whenever I click play, no matter what's in the project file, the program would be stuck on "Saving to..." and the top right corner would display "Building..." forever. I tried installing the newest runtime, but I just can't. Everytime I click install, it would download and nothing would happen. Please help me. Thank you so much. I am running Windows. Current runtime version is 22.214.171.1247, and my IDE version is 126.96.36.1995... I have no anti-virus program active. I save on my default location (in fear of messing something up) and have over 100GB free.
