Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
I'm having the same problems, but my system is perhaps too slow now!

Some pre LrC v10 plug-ins may not work in LrC v10. Some may break LrC. Of immediate note are the ones from jf. Updates probably exist. You can verify by bringing up the plugin manager, select each plugin, and see if LrC complains. I think an Adobe Tech was interested in that Folder Publisher for another members problems.
As fir the LogiOptions plugin, known buggy plugin. If you are just using your mouse/and or keyboard in a normal fashion, no need for that plugin, it allows you to assign LrC functions to buttons/etc
