Macbookpro(9,2) and Sequoia 15.3.2 and OCLP 0.6.5

Morning, sister-in-law pressed the updated button on Sequoia 15 but has steadfastly ignored the upgrade OCLP button.

Stuck on error below looping.

ApplekeyStore operation failed (sel 35, e000002f8, -1)

the sel: can be 7,24,35 etc...

I've booted into safe mode, run OCLP remove. Then installed version 2.2.0 and updated EFI and root patches but issue above continues. Can still boot into safe mode.

Looks like a kext/driver issue but not sure how to track down the offending file.

Any tips on resolving this one?

Cheers,
