Hiya! I got a warning message that asked if I could raise this as an issue, so here goes:

Warning message:
The size argument of element_line() is deprecated as of
ggplot2 3.4.0.
ℹ Please use the linewidth argument instead.
ℹ The deprecated feature was likely used in the patchwork
package.
Please report the issue at
https://github.com/thomasp85/patchwork/issues.
This warning is displayed once every 8 hours.
Call lifecycle::last_lifecycle_warnings() to see where this
warning was generated.

after running the lifecycle code I get:
[[1]]
<warning/lifecycle_warning_deprecated>
Warning:

This was the code I ran to generate the error:
layout<-c(
area(t=1,l=1,b=1,r=1),
area(t=2,l=1,b=2,r=1),
area(t=3,l=1,b=3,r=1),
area(t=1,l=2,b=3,r=2)
)

plot(layout)
