In short: Vivado can't opent .xsa
In long:
For this command: open_hw_platform
The result is this:
CRITICAL WARNING: [Platform 74-22] The XPM file <PATH TO>/Base_Zynq_MPSoC_wrapper.xsa could not be found.
ERROR: [Common 17-69] Command failed: Failed to read Xilinx Shell Archive. File does not appear to be a valid hw platform.
For this command: validate_hw_platform
The result is this:
CRITICAL WARNING: [Platform 74-22] The XPM file <PATH TO>/Base_Zynq_MPSoC_wrapper.xsa could not be found.
ERROR: [Common 17-69] Command failed: Failed to read Xilinx Shell Archive
This seems to me as such of a corrupted/not well exported XSA, however Vitis has no problem importing it!
(Oh yes and the xsa was exported from an example project provided by Vivado.)
