IFS block count critical (2)

Hello,

I am running the latest test firmware on my Nitrokey 3C NFC:
$ nitropy nk3 update --version v1.6.0-test.20231218

After activating the SE050 backend using:
$ nitropy nk3 set-config opcard.use_se050_backend true

And setting up the openPGP card.
I get an error testing the key.

Running tests for Nitrokey 3

[1/5] uuid UUID query SUCCESS
[2/5] version Firmware version query SUCCESS v1.6.0-test.20231218
[3/5] status Device status FAILURE IFS block count critical (2)
[4/5] se050 SE050 SKIPPED
[5/5] fido2 FIDO2 SUCCESS

5 tests, 3 successful, 1 skipped, 1 failed
Summary: 1 device(s) tested, 0 successful, 1 failed

Critical error:
Test failed for 1 device(s)

Before setting up the openPGP card, directly after the update, the test result is SUCCESS.
The behavior is reproducable by re-installing the firmware again and factory resetting the openPGP card.
