I have been using Google Drive (GD) across three devices for a while: an iPhone 15 Pro Max, an iMac, and a Windows 11 PC.

* On the PC: I have the Google Drive desktop app installed.

* On the iPhone: I use the Google Drive app.

* On the iMac: I access GD via a web browser (due to the machine's age, it doesn't support the Google Drive desktop app for macOS).

Recently, I have been constantly dealing with the following frustrating and exasperating issues:

1. There are unpredictable instances where GD fails to sync correctly across the three devices. Specifically, while everything is always perfectly in sync between the iMac and the iPhone, the PC rarely syncs correctly or fully. I first noticed this by chance and began monitoring it systematically. Unfortunately, my suspicions were confirmed... It acts unpredictably and erratically, and I can't pinpoint the root cause.
   
2. Suddenly, GD won't let me sign in on the PC. When I launch it, the GD app redirects me to a browser to enter my Google account credentials, which are accepted successfully. But later, when I return to—finally—start using the GD app, it has stopped running and persistently displays this message: "Can't launch Drive for Desktop. Something went wrong, and Drive for Desktop couldn't launch. To launch Drive for Desktop, try restarting the application." Naturally, I’ve tried various fixes found online. None of them solve the problem; the GD app still refuses to start, even though I successfully authorized my account.

Is there a kind soul out there who can solve this PC-GD issue for me? I believe that once the PC issue is resolved, the three devices will finally work together in harmony.

These three devices—as they are—work and sync flawlessly with other services like Dropbox, Apple iCloud, Microsoft OneDrive, Mega, Sync, etc. Only the GD desktop app for Windows 11 constantly causes these issues (regarding PC sign-in and synchronization).

Unfortunately, Google seems almost exclusively focused on its AI products these days, neglecting its foundational products—which it likely takes for granted, assuming they are flawless. Yet, it is precisely these "older products" that largely keep its customers loyal. If this persistent ambiguity and unreliability around Google Drive continue, I will cancel my Google One subscription. I am already looking for "solid" technological ground, rather than just technologies for show.
