Krita technicall difficulties - crash at startup

Recently Krita started crashing for me at startup - only 1 in 10 launches is successful.

The application shows splash screen end then exists without any error message. When launching app via terminaal I get the following log:

QObject::startTimer: Timers cannot have negative intervals
/usr/lib64/krita-python-libs/krita added to PYTHONPATH
KCrash: Application 'krita' crashing...
KCrash: Attempting to start /usr/libexec/drkonqi
Detected locale "LC_CTYPE=en_GB;LC_NUMERIC=en_GB;LC_TIME=en_GB;LC_COLLATE=en_GB;LC_MONETARY=pl_PL.UTF-8;LC_MESSAGES=en_GB;LC_PAPER=en_GB;LC_NAME=en_GB;LC_ADDRESS=pl_PL.UTF-8;LC_TELEPHONE=pl_PL.UTF-8;LC_MEASUREMENT=pl_PL.UTF-8;LC_IDENTIFICATION=en_GB" with character encoding "ISO-8859-1", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "en_GB.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

For successful launch log looks like this:

Object::startTimer: Timers cannot have negative intervals
/usr/lib64/krita-python-libs/krita added to PYTHONPATH
/usr/share/krita/pykrita/comics_project_management_tools/comics_exporter.py:432: SyntaxWarning: "\d" is an invalid escape sequence. Such sequences will not work in the future. Did you mean "\\d"? A raw string is also an option.
  svgRegExp = re.compile('[MLCSQHVATmlzcqshva]\d+\.?\d* \d+\.?\d*')

  string = re.sub("\<\/*?text.*?\>",'', str(v["text"]))
... (The log continues)

I am currently running Fedora 43 KDE (Plasma 6.5.1) with Krita version 5.2.11

At this point I am not sure if this is Krita issue or something is wrong with my enviroment - Does anyone encounter similar issue recently, or could help me debug this in any way?

Hi @apo

Are you using the official appimage from krita.org or is your Krita something your distro sent out? If you’re not on appimage, can you give that a try?
