Oak Shedding bark

[Binam]

Hi

We pollarded a mature Oak tree in southeast England last year in winter. It had severe wind damage and lost a very large limb. The tree is located right next to the children play area. Some other contractor has done work on the tree a few years ago before by heavily thinning the crown leaving excessive weights on the tip of the limbs that were overhanging the children play area. Since a few weeks, it has been shedding lots of barks. I have been monitoring since then. It could be weather stressed. We had an issue with the Hornets Nest at the root plate of the tree last few years. I think they were feeding on the sap?  There are few woodlice nest but I don't think they can cause any serious damage to tree health. It might be an early stage of Canker but still not sure. There is no sign of a bleed and cracks anywhere. A few days ago as I inspecting I came across white larve in the tree ( Picture attached ). We don't want to lose the tree but at the same time it is mature large tree right next to the children play area and if it on its way out we want to act before anything happens. Can you anyone advise or help please.
