Error compiling hello_world.cl with aoc

Hi,

since December 2019 (after an ubuntu update)

we have this error:

aoc device/hello_world.cl -o bin/hello_world.aocx

aoc: Running OpenCL parser....

aoc: Optimizing and doing static analysis of code...

Compiling for FPGA. This process may take a long time, please be patient.

Error (213009): File name "output_files/afu_fit.green_region.pmsf" does not exist or can't be read

Error: Quartus Prime Convert_programming_file was unsuccessful. 1 error, 0 warnings

Error (23031): Evaluation of Tcl script a10_partial_reconfig/flow.tcl unsuccessful

Error: Quartus Prime Shell was unsuccessful. 7 errors, 3326 warnings

Error: Compiler Error, not able to generate hardware

Is there any solution?

Thanks

Simon
