ffupdater keeps crashing on checking

[ffu-user]

As requested by app crash message, here it is following description of behaviour:

• app settings only accessible when phone in flight modus, otherwise app crashes too fast to enter it;
• in flight modus changed background / foreground settings, Check update on metered network

if Foreground: Update checks on metered: app crash and crash message

if no Foreground check, Background only, unmetered (but with no unmetered connection possible, so just checked without connecting) : no crash

The crash message:
