After a computer crash, when I had been using an older IDE version (I think 1.8.5) I spent a great deal of time unsuccessfully re-loading and re-installing 1.8.12 and 1.8.5, both with and without turning off the Windows Defender virus protection. (I'm using Windows 10.)
None would get past a brief appearance of the IDE initial screen.
FINALLY found (on this forum) that 1.8.13 was available; try it and see if that solves the problem.
Answer - I did, and IT DOES!
