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!
Thanks

macOS Big Sur requires Xojo 2019r3.2 minimum.

Thank you.
