I rectify what I wrote previously because doing several things at the same time, I was wrong and what I did can serve others ..
I could not find the scripts of Alpha to logo in Gimp-2.10.8_Port \ Preferences \ scripts but I found them in Gimp-2.10.8_Port \ share \ gimp \ 2.0 \ scripts so I copied the 49 files in Gimp- 2.10.9_Port_20190317 \ share \ gimp \ 2.0 \ scripts
and they appear well in the Gimp 2.10.9

Good to hear. Remember to keep a backup of your personal Gimp files and settings so you don't have to track down everything again.
Nidhogg, I save everything but I can not find....

then so I just made a clearer storage!
