Linking Executable Error

I installed Xojo Version 2022 Release 4.1 yesterday. I worked with Realbasic some 10+ years ago and would like to return to the Xojo IDE.

When I try to run a completely empty project I get the cryptic error message “Linking Executable”. Without any further description or hint to what causes this problem.

The problem may be that I am using an iMac Late 2009 (…) with 8GB RAM and 512 GG SSD that is patched with the DosDude tool to (perfectly and smoothly!) run MacOS 10.15.7 Catalina.

I also installed Xcode 12.4 (i.e. the latest Xcode version for Catalina), which runs slow but also smoothly.

Anybody’s help would be greatly appreciated!
