When I was trying to set up a hanger with molly bolts, for some strange reason one of the molly bolts crumbled the drywall around the hole when I expanded the plug.
So now I have an expanded molly bolt in a damaged hole in the wall
What options do I have to fix my problem? Is there some kind of larger plugs that can be placed in the hole?
I can push the plug into the wall, but then I still have a damaged drywall hole where I still want to attach my hanger.
I gladly welcome any tips and advice so we can finish renovating our hallway.

The first question is how you expanded the plug? Did you use a tool made for the purpose, or did you simply tighten the screw until the plug expanded? If you used the latter method, it's not uncommon for failures to occur.
Regarding repairs, I would suggest pushing the plug into the wall and repairing the wall with something like husfix. I have personally fixed slightly larger holes by pushing a small piece of board or chipboard into the hole, screwing it in place with screws around the hole, then filling with husfix. Usually, it's necessary to reapply husfix a second time to get a smooth surface.
Your hole is probably a bit too small to fit a piece of wood into it, maybe just filling it with husfix will suffice.
I would almost think you don't need any plug if you screw directly into the husfix afterward. But perhaps you should test that first. Make a small piece of "wall" with the husfix left over after filling, and try screwing directly into it (maybe pre-drill).

Thank you for the response,
Yes, I used a molly plug tool to expand the plug as it usually works well.
I didn't think that husfix was so strong that it could fix such damage.
Definitely worth trying, so I will probably surf around a bit and check info about husfix.

Some plasterboards are quite impossible to attach to because they are too soft, i.e., budget boards.
In some cases, I have used gypsum mortar with mineral wool as reinforcement for it and then foamed behind with PU foam to get adhesion against a larger surface area; however, this method should be used with caution as it can blow out the wall. A support that presses the repaired part tightly against the wall is a must.

In this case, it is an old wall, i.e., a wall that has been there since the house was built nearly 20 years ago. So I don't want to make too big of a job out of this because the hallway has been recently fixed up with wallpapering, painting, etc.
I wouldn't be worried about the strength of the house fix, possibly about how well it is attached to the drywall, i.e., I don't think you need to reinforce the fix, the risk is more if the whole chunk comes off later.
I have now fixed my molly plug hole.
Here's how I did it:
I pushed the collapsed molly plug into the wall and filed the hole slightly conically on the backside. I mixed house fix and put some in a regular freezer bag. I cut off one of the corners of the bag and used it as a piping bag. I piped plenty of house fix around inside the hole as far back as I could reach and filled it up until the entire hole was filled. I smoothed the surface with a putty knife.
After the drying time, I tested the strength on a test piece that I had made the same way as with the wall. The conclusion was that if you pre-drill with the same diameter as the core of the screw, it worked really well to screw directly into it. If you drilled a slightly too small hole, there was a slight tendency for cracking around the screw.
So to be on the safe side, I drilled and inserted a brown plastic anchor with very good results.
Thanks for all the advice and tips
