Xojo 2019 R1 on Big Sur

Good morning,
I get the following error with Xojo 2019 R1 on Big Sur.
Linking Executable
ld: file not found: /System/Library/PrivateFrameworks/UIFoundation.framework/Versions/A/UIFoundation for architecture x86_64
Is there a way around this or is it upgrade time!

macOS Big Sur requires Xojo 2019r3.2 minimum.

Thank you.

If you want some more details on why, read about it in this recent thread.
