Steps to reproduce the issue:

Run following code, step-by-step:

ff <- "mo(gear)"
ff <- stats::as.formula(paste0("~", ff))
ff

First, the value of ff appears in the Variables view. After converting to formula, the value changes to ??.

What did you expect to happen?

The value of ff changes to ~mo(gear).

Were there any error messages in the Output panel or Developer Tools console?

No.

Notes for when we look at this:

From my perspective the main problem is that formulas and other objects like quosures have length > 1 but base::format() results of length 1:

x <- formula(y ~ a + b + c)
length(x)
#> [1] 3
length(base::format(x))
#> [1] 1
