Carefully undo the latches so you can squeeze some silicone between the glass. Tighten back up and let it dry, should help. You can throw some shims under the glass to keep it from skidding down while it dries (usually a day or so). Just be careful no to hit the edge of the glass.
Lubricate when necessary
If your shower door hardware squeaks or doesn't move smoothly, you can lubricate it with a silicone lubricant. Apply a small amount of the lubricant to the hinges, rollers, or tracks and move the hardware back and forth to distribute it evenly.
Apply a silicone-based lubricant to the tracks and rollers of the shower door to reduce friction and promote smooth movement. Avoid using oil-based lubricants as they can attract dust and debris, which may further contribute to the buildup of grime.
Sometimes the shower door roller unit may be stiff or stuck on the door in which case you may find it useful to use a light spray lubricant, such as WD40, and let this soak into the joints of the unit for a while. In certain cases you may need to re-apply the lubricant a few times and leave overnight to soak in.
One of the most recommended lubricants for sliding glass doors is silicone-based sliding door grease. This type of lubricant offers excellent durability and water resistance, making it suitable for both indoor and outdoor applications.
Use a metal needle tip applicator to get a few drops of lube into the door hinge you can reach. You can wipe off any excess lubricant. You will find that AIM is not like WD-40 or other aerosol sprays that result in a large volume of spray being applied and then requiring cleanup. A small amount of AIM goes a long way.
Vaseline acts as a lubricant, and applying a thin layer of the gel to the tracks of sliding glass doors can help maintain smooth and effortless operation.

Glass shower doors can sometimes become difficult to open or close smoothly. This can be due to a buildup of soap scum, hard water deposits, or dirt in the tracks and hinges. Regular cleaning and lubrication of the tracks and hinges can keep your door operating smoothly and prevent sticking.
One of those rubber or silicone mats with suction cups on the back side. Good grip underfoot and they don't slip around in the shower.

If your doors have vinyl tracks, be sure to use a lubricant that's silicone-based and non-stick. A silicone, non-stick lubricant is essential for vinyl tracks so the door slides easily and the lubricant doesn't attract dirt that can cause a clog in the track.
Dust, pet hair, and other debris can create buildup that slows down and hinders your door's sliding motion. Vacuum this area using the crevice tool and scrub gently with a stiff brush to remove any caked-on material. Wipe the track clean with a damp cloth and let it dry before sliding the door.
