Strange complilation issues with CLA bock in Matlab 2021b using F28379D

Dear Mathwork community,

Recently after switching to Matlab2021b for the past 3 weeks, we are getting very strange compilation errors while the CLA block is included, before anything I should say:

1. The code works perferctly on matlab 2019b
2. All the memory assignements in CLA ( the inputs and all the delay functions and so on) are done based on the guides on CLA based on this, the cmd file and the rest are also fully compliying
3. We are using CLA block and not the inlined function for CLA (BTW, the error appears in both)
4. I can't share the code here as it's huge and many other concerns.
5. Once we comment the CLA block the code compiles ( no change in project settings)
6. by putting an Empty CLA block in the same place the code shows the same compilation errors, so the problem is not the code within the CLA

The error is and to me it's impossilbe to track down where it's happeneing ( of course I checked the TLC files that it refers but it's not feasible to undrestand what is the cause od this error)

I belive this error should be due to some project settings, but what can be the cause is unknown and we appriciate your help for that.

I would suggest you to use the Upgrade Advisor tool for upgrading the model to work with the newer realease - https://www.mathworks.com/help/simulink/slref/upgradeadvisor.html
