What is the problem?

Upgraded cdk to v1.33.0 and when I try to synthesise a project I get the following error:

Traceback (most recent call last): File “/Users/myusername/repos/cdk_myproject/app.py”, line 2, in <module> from aws_cdk import ( File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_ec2/init.py”, line 1443, in <module> from ._jsii import * File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_ec2/_jsii/init.py”, line 11, in <module> import aws_cdk.aws_cloudwatch._jsii File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_cloudwatch/init.py”, line 495, in <module> from ._jsii import * File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_cloudwatch/_jsii/init.py”, line 11, in <module> import aws_cdk.aws_iam._jsii File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_iam/init.py”, line 484, in <module> from ._jsii import * File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/aws_iam/_jsii/init.py”, line 11, in <module> import aws_cdk.core._jsii File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/core/init.py”, line 17379, in <module> class Construct( File “/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/aws_cdk/core/init.py”, line 17432, in Construct def _on_synthesize(self, session: constructs.ISynthesisSession) -> None: AttributeError: module ‘constructs’ has no attribute ‘ISynthesisSession’ Subprocess exited with error 1

Nevermind, removed all the pip modules and installed them again. Something must have went wrong with an upgrade I imagine.
