Analyzing buy RAD C ++ Builder 10.2

I'm trying out your RAD 10.2 Tokyo C ++ Builder Starter product. But I have encountered an anomaly. I want to know if I can get C ++ Builder Starter from previous version to investigate if the problem found in 10.2 has been solved in previous versions. Beforehand I know that if I require a previous professional version, I must buy professional RAD 10.2. I just want to know the Starter version of previous products. Thanks in advance.
