I have been able to take control of the pen on the intuos pro tablet, for this I have done the following:
Disable the antivirus, (VirusBarrier)
Reload the Driver 22.214.171.124, (the one that was installed when the pen was working).
Reset the preferences of Kyma and return them to configure as they had before, exactly as detailed in the question "Wacom Tablet still not working". (Thanks to those who participated in this question).
But only with this way the pencil still did not work, I had to do a second operation, go to Wacom Tablet Utility and erase the preferences (thanks Matthew Carpenter).
I do not know the reason, but it seems on my computer there is an incompatibility between VirusBarrier (recently updated) and Kyma. When VirusBarrier is activated, Kyma takes a long time to load and the pen does not work and when I disconnect it, kyma is loaded normally and the pen works.
