Issue created: SPE-1699

The crash - at least for me - occurs on line 162 (and same problem also noticed on line 170) of /src/slic3r/GUI/ConfigWizard.cpp when the
\PrusaSlicer-beta\cache\EvoLabs.idx cannot be found after I copied my custom Vendor profile files, including EvoLabs.idx file (that work in PrusaSlicer 2.5.2 installed on the same machine), into C:\Users\{User Name}\AppData\Roaming\PrusaSlicer-beta\vendor prior to running a debug session.

If I remove my custom Vendor profile files, the Configuration Wizard window appears without error.

Problem

format function failing because it's expecting 2 placeholders instead of just 1:

if (!boost::filesystem::exists(idx_path)) {
    BOOST_LOG_TRIVIAL(error) << format("Could not load bundle %1% due to missing index %1%.", id, idx_path.string());
    continue;
}

Fix

1. Include 2nd place holder in the format string:

BOOST_LOG_TRIVIAL(error) << format("Could not load bundle %1% due to missing index %2%.", id,idx_path.string());

2. Make sure custom profile .idx file (e.g. EvoLabs.idx) is copied to \PrusaSlicer-beta\cache\, in addition to \PrusaSlicer-beta\vendor\
