Crash in Clip multiple rasters function because of CRS error

[Go-Tak]

win11(64)
QGIS:3.16.12-Hannover
python 3.7

When press Run button of Clip multiple raster, I got the following error message.
#########
AttributeError: 'NoneType' object has no attribute 'replace'
Traceback (most recent call last):
File "C:/Users/go_ta/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\clipmultiplerasters.py", line 82, in clipRastersAction
self.clipRasters()
File "C:/Users/go_ta/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\maininterface\clipmultiplerasters.py", line 230, in clipRasters
eCrs = cfg.utls.getCrsGDAL(l)
File "C:/Users/go_ta/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\core\utils.py", line 7360, in getCrsGDAL
return crs.replace(' ', '')
AttributeError: 'NoneType' object has no attribute 'replace'
#########

Then I tried to identify the place of error occurred by adding the codes in utils.py located under core directory.

Finally I found that error occurred in this statement crs = l.GetProjection(). Although this statement works fine in Jupyter.

I don't know why the above simple statement cause an error.

Does someone know the way to solve this issue?

Hello and thank you for reporting this issue.
Possibly , it could be related to this QGIS issue https://lists.osgeo.org/pipermail/qgis-developer/2021-November/064212.html
Possibly you could try to install a previous version of QGIS.
However, I'll look into this.

Also, please copy the log file following these steps https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#how-can-i-report-an-error

Thank you for the response.

I tried version 3.14 & 3.18 although both failed and the screen of Clip multiple rasters freezes.

I tried to get a log information as you indicated and attached below.

I also attach the error message when executed l.GetProjection() without try -except trap.

When I see the Error.txt, it seems that there is different PROJ installed. Then I remember that I have 2 Python, one is Anaconda Python and the other is straight Python. I don't know how to set Python library used in QGIS and QGIS plugin.

Although both python version is not 3.7.0 as recorded in error message, Anaconda Python is 3.7.10 and the other 3.7.6.

Sorry to bother you.

I solved this error by setting environment variable PROJ_LIB to a value of %PROJ_LIB% variable.

Thank you very much for your feedback.
I'm glad that you solved the error.
