RPI 4B Flashing LED Test Compile Fail

Just purchased the RPI/PICO component bundle and did a quick LED flash test using the RPI 4B.
Simulation is fine. Build to HEX compile fails immediately.
RPI_CAL_String.c fail
Don't think the problem is my toolchain. Could someone quickly check.
All the files are attached in the zip.
Thanks
Charles

I've not had chance to check your zip yet.
But have you tried a full database update?
The CAL string files have had some changes recently.

Yes I just did a full update and the compilation error is still there unfortunately.

Looks like RPI_CAL_String.c is missing the FCLsz_TEMPSTR fix and other updates - one for Ben
