XYplorer Beta Club
In my case, many problems have been solved with the latest beta version.
We'll have to wait and see, but so far, the problems we've had before have not appeared.
The same goes for Error 16.
The slow generation of thumbnails has also been resolved.
But besides installing the beta version
I deleted and reinstalled ICAROS, deleted all the ICAROS cache files
I set the ICAROS cache mode dynamically.
I am really grateful to the developers for solving the problem.
