Same bug here. Here's my notes for the workaround which works great at least until this gets resolved.
Steps needs to be followed in the order below... I've numbered them to help with that.
Step 1: Create a New STM32CubeIDE Project
1) In STM32CubeIDE > File > New > Select Part Number > Next > Set ProjectName > Click Finish
2) Enable SYS > Serial Wire (other configs can be made later)
3) Save and close ProjectName.IOC
4) Build Project (Compiling should be successful!)
Step 2: Add TouchGFX 4.17 to the Project
5) Open ProjectName.IOC > Enable CRC > Software Packs > Select Component > TouchGFX 4.17
6) Expand Software Packs > Enable Graphic Application > *LEAVE ALL TouchGFX SETTINGS TO DEFAULT*
7) Save and close IOC *DO NOT BUILD THE PROJECT *
Step 3: Generate TouchGFX 4.17 Templates
8) Double-click on \TouchGFX\ApplicationTemplate.touchgfx.part
9) Select "Blank UI" > Click red Import button > Click Generate Code > Close Designer using the X
Step 4: Clean & Compile Project
10) Right-click ProjectName > Select "Clean Project"
11) Right-click ProjectName > Select "Build Project" (Compiling should be successful at this stage!)
Step 5: ToughGFX Configurations and Code generation
12) Open ProjectName.IOC > Software Packs > TouchGFX > Set Screen Resolution e.g. 240x240, etc
13) Double-click on \TouchGFX\ApplicationTemplate.touchgfx.part, Click Generate Code > Close Designer using the X
14) Right-click ProjectName > Select "Clean Project"
15) Right-click ProjectName > Select "Build Project" (Compiling should be successful at this stage!)
done!
Note: If Partial Buffer is required and selected in the TouchGFX configs:
16) Move attached "TouchGFX_DataTransfer.h" and "TouchGFX_DataTransfer.c" into the \TouchGFX\target\ folder
17) CLEAN PROJECT and Build Project
