systemd service fails to start script in home directory

I would like to start a python script (i.e. a Flask server) at boot of Ubuntu 22.04. I have created a file /lib/systemd/system/myService.service with following content:

[Unit]Description=The service starts a Flask server[Service]User=myUsernameExecStart=/home/myUsername/PycharmProjects/myProject/server/server.sh[Install]WantedBy=multi-user.target

server.sh contains the following content:

#!/bin/basheval "$(conda shell.bash hook)"conda activate huggingfacepython server.py

When I start the service, I'm getting the following error:

Mar 28 02:04:39 myComputer systemd[1]: Started myService.Mar 28 02:04:39 myComputer  systemd[1713428]: myService.service: Failed to locate executable /home/myUsername/PycharmProjects/myProject/server/server.sh: Permission deniedMar 28 02:04:39 myComputer  systemd[1713428]: myService.service: Failed at step EXEC spawning /home/myUsername/PycharmProjects/myProject/server/server.sh: Permission deniedMar 28 02:04:39 myComputer  systemd[1]: myService.service: Main process exited, code=exited, status=203/EXECMar 28 02:04:39 myComputer  systemd[1]: myService.service: Failed with result 'exit-code'.

When I directly execute server.sh it works, so the problem is the service. I think that the problem could be that I want to start the script in my home directory.

Is there a possibility to get the service to start the server.sh in my home directory? I don't want to move it outside of my home because other users have access to the computer and they should not have access to the files.
