If you have not already gone to the computer nerds for repair, and that is a very good idea, then a few things to look at (the nerds will probably do this). Oh, and windows profiles can get corrupted, but your issue is probably in the windows registry (we will not go deep into that, registry repair by non nerds either needs registry repair/maintenance software or very very good knowledge on what you are doing and a acceptance to take responsibility if it goes very wrong), moving on. 1. Probably best if you re-do your cold boot before doing the fowling snooping. SYMPTOMS IN PROCESSES/APPS RUNNING 2. After the PC starts, do not at first launch Adobe Photoshop Lightroom Classic. Lets do an initial step. 3. At the same time press the following keyboard keys: CTRL ALT DELETE The taskbar will come up, click on Task Manager. If it is not by default already selected, select the Processes tab. Pay attention to the Apps. Is "Adobe Photoshop Lightroom Classic" stated as running? Should not be yet. If it is, then click on it as to select it, then right click and select End Task While still in the Task Manager, go to the tab Details and see if Lightroom.exe is listed as running. It should not at this point. 4. Close the task manager, sometimes it does not take refreshes very efficiently and you may be happier relaunching it instead when called for. Now go and attempt to launch Lightroom, while it fails (I assume) go back to the Task Manager, see that only one instance of "Adobe Photoshop Lightroom Classic" is running under Processes/Apps, and only one instance of Lightroom.exe appears in Details. If more than one is running, again end those task, repeat and see if the issue reoccurs. If this is happening, get to that store, let them know, and they will fix. By the way, have a fresh memory of your Adobe login when you go to the store, they might in the end have you login to reload a fresh copy of LR. SYMPTOMS IN EVENTS 5. Moving on. On your screen, bottom left,the windows icon that you might normally left click to bring up applications, right click on it, left click on Event Viewer. Wait for the summary to populate. do not get all tied up in Oh my gosh, issues, lots of reasons for issues to be represented in these logs, not all are the end of the world. Now over on the left, note the item "Windows Logs", click on it,Click on Application. Note any error, those today, probably in the last hour or less. See if any relate to Lightroom (note application path). This might give a clue, might not, might be all in nerd speak. Re-post any error from that log.\
