As you can see, the port you are probably using, is an input port for a wired remote control, not an output port for flash sync.
You may make it work, if you connect one flash onto the hotshoe and set the other flashes on optical triggering if they support that.

I'm making an educated guess that the FC-16 triggers you have are rebranded 2.4 MHz Godox FC-16 triggers, since that's what I see packaged with your speedlight model (which is not a rebranded Godox speedlight) on Amazon.
No speedlight uses a 6.5mm connector. So, I assume a studio strobe/monolight is being used, here. You've probably got the cable plugged ...

My guess is that some electrical connection inside the lens looses contact in some mechanical situations, maybe getting stretched when going beyond 200mm focal length.
The over-exposure might come from such a faulty internal connection: the iris not closing, thus taking the photo full-open at f/5.6 although commanded to do f/11. This would result in a two-...

This was going to be a comment.
As the lens is extended, the "lever arm" gets longer. Maybe the rear lens flange is a bit loose and is creating a gap at the longer focal length leading to improper electrical connection.
I would recommend close inspection of the lens to camera connection as the lens is extended as a first step.

I don't think there is a specific max weight for the lens mount, as such, I've never really seen that on any camera I've owned (modern or film) as typically heavy lenses should be supported directly and not via the camera body.
While the M50 mount is welded to the inner metal frame, this not is heavy duty. I would not recommend supporting a heavy lens with ...

Throw the MicroSD card. Or use it for something not important as MicroSD, not with adapter. Adapter is other device (passive but intermediate) and can cause some unpleasant side effects. Your camera is for SD cards so buy SD card and use it.
The problem with camera can be caused by battery not keeping the charge (battery with end of charging resource, ...

The Canon RT radio system and the Godox X radio system both use the 2.4GHz radio spectrum to transmit and receive. The signals they are transmitting and receiving over 2.4GHz, however, are not compatible as they use different protocols.
In other words, they're like two people trying to communicate over walkie talkies on the same channel but one is speaking ...

The Canon RT system the 430EX III-RT uses is not the same radio system the Godox 2.4 GHz transmitters use. Frequency band (2.4 GHz) alone is not enough to guarantee compatibility. And even brand alone is not enough to guarantee compatibility. The two triggering systems between your transmitter and your flash have to match.
You can add a Godox X1R-C receiver ...

The Godox X2T uses a different protocol than your Canon Speedlites. You cannot directly trigger them with said wireless trigger. In fact almost all brands use different wireless protocols - so they usually are not compatible with each other.
You can, however, attach a X1R-C receiver to the 430EX II. This unit acts as a receiver and works with the Godox 2.4 ...

As others have already mentioned here, Canon batteries use an identification chip that "proves" that the battery is a genuine Canon battery (though these schemes invariably get broken pretty quickly).
Unfortunately, Canon's overly aggressive attempt at protecting battery sales causes serious problems because:
Some real batteries (third-party only, ...
