Try to upgrade to a higher version as much as possible. Most people no longer use the lower versions. Many issues cannot be reproduced without the same version, which will affect your efficiency in solving problems. Additionally, many issues in the lower versions have already been resolved in the higher versions. So, the answer to many of your queries might simply be: it’s a bug, and upgrading to a higher version will solve the problem.

Unable to start, can’t upgrade, right?
