Cannot import name 'solve_triangular' from 'pytensor.tensor.linalg'

Using Anaconda environment, python 3.10. Created a separate environment and installed PyMC using Conda install PyMC.

Can you please help. Last time I imported PyMC in the same environment and everything worked fine. I dont know why PYMC creates an import issue everytime I import it especially when switching environments even though I make sure it is installed in every environment.
