I'm trying to sync my Canon eos 250d with our studio strobe light through Godox TT520II Speedlite, but it won't work? Any solution?
You can mount the TT520II on top of a Godox X1T-C that's been firmware updated for compatibility with the Canon hotshoes that are missing the sync connector. The TT520 II only has the sync pin on its foot, so it can't communicate with your camera directly on the hotshoe.
But. You could also use your pop-up flash in M mode with the studio strobe's optical slave. Or just get a Godox speedlight.

This is a logical assumption, but incorrect. The TT520ii (aka TT560 II) is using an older 433 MHz radio trigger, which is incompatible with the current Godox 2.4 GHz "X" system. It will not work together over radio with an X1T-C. The equivalent newer model to the TT520ii would be the $60 TT600. But I would recommend a $110 TT685-C instead, which is full TTL/HSS, has 360º swivel, and is firmware updateable. It's a much better, more versatile unit, since TTL means using it both on-camera bouncing and off-camera flash is much easier. Most TTL speedlights can be put into M; no single-pin manual cheapie can do TTL/HSS on a hotshoe.
If the studio strobe is an older Godox model using an FTR16 USB-A receiver, there is a 2.4 GHz drop-in replacement, the XTR16, but power control might get wonky, since the transmitters use flash ratios (1, 1/2, etc.) not the percentage controls on the older Godox lights. The Godox AC strobes that are Mk II, Mk III, or the MS series have all been updated with built-in 2.4 GHz receivers that work directly with Godox's 2.4 GHz transmitters.
