Failed to install org.gnome.Sdk

I’m trying to install Gnome Builder but I keep getting the error shown below:

Error: While pulling runtime/org.gnome.Sdk/x86_64/3.38 from remote flathub: opcode open-splice-and-close: opcode close: Corrupted file object; checksum expected='47347db08c3e959cfaad3c37f38cfd9843fc9c1200afec0e735d6a116dd0643e' actual='dcd682e6f6df1c08cc478c995a704c7af7a4b48f09d10a6f26c78c1695e43363'
