I suddenly had a problem with warp stabilizer.
It begans with an old project from an old version where premiere requested me to re-analyze footage and then it never finished stabilization: orange bar never disappeared.
I solved the problem opening a new project and then importing the old project as a source inside the new version. In this way stabilization worked.
But now, not only my old project with old versions doesn't work, but also if I open a new project, I take a clip, make a sequence with the clip and try to stabilize, the stabilization never finished and the orange bar is fixed on the clip. If I close the program, the premiere process goes on to work, and I have to force the closure.
I tried to update to last version, I tried to reinstall premiere and all updates but the problem is still the same.
That's a big problem cause I have a lot of project with warp stabilizer that I even have to deliver quickly.
