OpenCore stalls before displaying picker (possible issue with partition scanning)

[badziew]

Hello,

since some time (probably after some OS update), I have a problem where 9 out of 10 times, OpenCore will stop at black screen before displaying picker. Sometimes, however, it will proceed and the OS will boot normally.

I have finally cleaned up the OC logs and managed to collect logs from failed and successful OC starts (attached).

It seems like each time OC stalls, the final entries in log look like this:

whereas with successful boot, the same section looks as follows:

You can see that the "Matched fs" shows a different hex string between failed and successful starts. With each failed start, the string is the same.

Could you please help me in resolving this problem.
