PC Controller losing connection intermittently

[Irohma]

The problem returns. I've played with a controller since at least 2015 and this issue was always there. Once in a while the controller would not respond for a second and then it would get back to normal. This was rare though, most likely happening in my first few minutes after booting the game and then not ever again during the day.

Now, after the latest patch, this has made the game almost unplayable. The controller stops responding every minute or so, sometimes twice in a row. I've attempted every possible solution in this topic and beyond to no avail. As with almost everyone else, this does not happen in any other game I've tried. In fact, it was a minor issue in FFXIV itself prior to patch 6.3 for me.

Platform?
Windows 11 (Steam)

Which controllers specifically did you try?
Dualshock 4, both on Bluetooth and wired (wired was my standard way of playing the game before)
Xbox One Controller, on Bluetooth.

When using wired method, did you disable any bluetooth options to avoid interference?
Yes.

Do you have multiple controllers or other 3rd party devices hooked up the machine?
No. Only one controller at a time was connected to my PC.

Did anything change in the computer's environment that may have contributed to the problem?
No. Game was playing fine right up until patch 6.3.

Try running a clean boot on the machine to see if that may help (disable any programs that may be interfering with the game such as discord if applicable)
No change. Multiple boots, multiple attempts with and without other programs running. The controller stills loses connection once or twice every minute.

Wired or wireless connection:
Tried both with a DS4 Controller and via bluetooth with a Xbox One controller.

Internet Service Provider:
Vivo.
