QGIS 3.34 Python Error

[paskiller]

Hi.
I installed OSGeo4S and QGIS 3.34. When I open QGIS I have this error:

Python Error: Failed to load plugin 'crayfish' due to error calling classFactory() method. See the message log (Python Error) for more details.

Error:

How can I fix it ?

Last line shows error that caused the failure.
all of the previous lines are order of execution that preceeded the error.

Read 'time' doc.

suggest you contact author of 'crayfish' his email address can be found here in PiPi.org

What version of crayfish do you use? Latest 3.6.0 (actually starting with 3.5.1) says added support for python 3.9+
time.clock() was removed in 3.8

Looking further, you definitely use version like 3.5.0 or lower
