Macbook pro keyboard mis-typing

MacBook pro 2016 15inch. Recently updated to big sur within a days keyboard issues arise.

Keys in the outer columns (`, tab, caps lock, shift, fn) work fine on both left and right side.

Keys in the upper most, and lower most rows work fine.

Additional keys with no issues: "[" "]" "," ";" "/" and associated caps

The issue arises with the letter keys.

Example pressing "a" output is "aqz". Letters which are above and below 'a'

f = frv

h = hny

v = fvr

t = bgt

and so on.

It seems like hardware failure to me, but I thought Id ask about it.

thoughts? TIA
