Can't run GNS3 on Ubuntu 21.04

When I run GNS3 as user (in admin group) on Ubuntu 21.04, I get this error messsage:

2021-08-24 12:16:54 INFO root:126 Log level: INFO 2021-08-24 12:16:54 INFO main:259 GNS3 GUI version 2.2.23 2021-08-24 12:16:54 INFO main:260 Copyright (c) 2007-2021 GNS3 Technologies Inc. 2021-08-24 12:16:54 INFO main:261 Application started with /usr/bin/gns3 /usr/share/gns3/gns3-gui/bin/python: symbol lookup error: /home/_________/.local/lib/python3.9/site-packages/PyQt5/Qt5/plugins/imageformats/libqsvg.so: undefined symbol: _ZdlPvm, version Qt_5

When I run it as root, works as expected.

Any ideas?
