LRC does not respond in edit mode anymore

[BramtK]

I installed recent LRC V10. After a few days it does not respond en blocks as soon as I open a photo in the editmode. I work with a desktop, W10 home.

First, please try if it helps to reset the preferences:

Unfortunately, that did not improve. But thanks.

In the mean while I am thinking the problem must have something to do with the preferences. Some of them have been imported in tutorials even in LR6 earlyer.

How to erase them?

The devoloper mode/ right sidebar is working without problems! 

Do you have any suggestion?

I think the problem was the presets that came with a course from zoom.nl that created the problems. I have erased them and now the problem seems to have disappeared. The remaining preset do function without a problem.
