Help! I just got a new Macbook Pro. I restored my Time Machine backup from my iMac. I went to open Lightroom 6.14 (serialized), and it prompted me to install Rosetta because of the new Apple M1 chip. I did that and Lightroom opened fine. The problem is, when I closed lightroom, it took forever to close, then I got a popup telling me that the program closed unexpectedly. Now, anytime I try to open it, the splash screen flashes up on my desktop for a fraction of a second and then disappears. No matter how many times I try, lightroom will no longer open.
Yes, I see you tried with some success to restore via Time Machine, as opposed to a install that would not have worked at all. However members with pre M1 and pre Catalina, much less Monterey, trying to do that Time Machine restore, usually show up in this community as Lr6 not working at all, much less once.
program closed unexpectedly.
One thing to look at, a lock file that did not get deleted.
