fvim crashes when neovim closes due to file already open

[siddhi]

I had a file open in fvim.

Opened it again in another window and got the usual message "Found a swap file, Do you want to (O)pen Read Only, (E)dit anyway, (R)ecover, (Q)uit, (A)bort"

When I select quit or abort, then neovim closes, which causes fvim to crash

Expected: fvim should close normally without a crash

Error

The neovim process exited abnormally

Can repro:

Exit code: 1
Exception message: neovim crashed

But I wonder if this is by-design because it's a non-zero exit code which indicates some error?

:help exiting

When using `:cquit` or when there was an error message Vim exits with exit
code 1.  Errors can be avoided by using `:silent!` or with `:catch`.

So exit code 1 is properly defined and not a crash.
