I keep getting a bug whilst changing modules where Lightroom will not respond and I have to close and reopen. I get the error message below and clicking OK does nothing. I'm using a 2017 iMac running Sierra version 10.12.6, any ideas?
Further information. This is on a late 2103 Mac Book Pro (retina) running High Sierra.
Every three or four LR starts takes we to the welcome screen instead of the last thing I worked on. Clicking OK in the tip results in a screen presentation similar if not identical to the initial screen on a fresh installation. In particular, my account information is missing. Trying to switch to the library causes the Error Changing Modes condition.
Restarting LR usually takes me back to a working session that has my full account info and shows the last picture I worked on.
Why does LR randomly revert to this initial state? It is related to the new LR version being targeted for cloud operation?
In my opinion this is a major flaw in the LR Classic release.
