Lightroom crashes/freezing when using presets

[karinb45429596]

After the last update I cannot use my presets properly on my mac. Is there already a solution? It realy complicates my workflow. Help!

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.
