We can’t see why your brake is clamped on pictures. It is mostly a stuck cilinder because of corrosion or dirt. It is sometimes the cilinder’s adjusting feature going rogue because of oil on your brake pads.
Do a full service on your brake: Take the cilinder off the mount. Remove the pads. Oil the cilinders. Pull the brake while holding something between the cilinders. Now if you can’t easily push back the cilinders then they are stuck. Then you need to replace the brake. If you can push them back, then oiling and moving them has solved your issue. Continue by cleaning them of all the oil. Put in new brake pads. Degrease the disc. Assemble the brake back in its mount.
If after this your brake feels squishy, bleed the brake.
Or bring it to a shop.

Well it looks like the pistons pushed out and did not retract . Thus the pads have grabbed the rotor. I would either remove the wheel or caliper from the fork, remove the pads, open the bleed port at lever (place rag over same) and with a large flat screwdriver force the pistons apart. Find a YouTube video or three as well. I’m gonna go out on a limb and say the Pistons probably need to be cleaned otherwise this will continue to happen.
Or I could be completely wrong and perhaps the rotor is badly bent and jammed into the pads.

Your brake pads are worn.
