Formula command only gives error in vscode-R

[arbreazeale]

Describe the bug

When using Formula() in vscode-R (but not when running R/radian directly or RStudio), attempts to set any formula gives "the condition has length > 1" which repeats until crash (even when using non-Formula commands like y <- 1).

To Reproduce

1. Launch an R session from VSCode (not using a terminal command, but within the app). I've done this by (a) running a chunk from within an .Rmd file and (b) Terminal > + (dropdown) > R Terminal.
2. Enter the following code:

library("Formula")
f <- y ~ x
F <- Formula(f)

3. See error "the condition has length > 1"

Can you fix this issue by yourself? (We appreciate the help)

No (I wish I could, but that's outside the realm of my knowledge)

Expected behavior
The command should run without issue and create the F object in the environment.
