I don't know what happened with my message, so here it is again in case you didn't get the one before this:
This version logs everything related to icons into a file in \Log folder. Extract it in a separate folder, run, make sure that the version in corner is
3.1.18.1 and browse folder just until you see icons stop showing. At that point, right-click on tray icon and click e Open Log and scroll to the end
[12:33:55 INF] C:\Users\milos\Downloads\OfficeSetup.exe Extracting True
[12:33:55 INF] C:\Users\milos\Downloads\OfficeSetup.exe Done True
[12:33:55 INF] C:\Users\milos\Downloads\OfficeSetup.exe Extracting True
[12:33:55 INF] C:\Users\milos\Downloads\OfficeSetup.exe Done True
I am looking for one with "Extracting" without following with a line "Done" or "None", or an error message.
This version is very slow, so icons will slowly appear, so even if you stop seeing icons, wait a few seconds to confirm that it is not writing to a file that is causing this.
You can close OC, delete the log, and run it again to check if the next time another file breaks it. Don't use if afterwards, as the log file will grow huge
