Slow virtualbox startup

After some update i noticed that virtualbox interface takes too much time to start (about 30 seconds), and once it has successfully started it behaves normally until the next start.

There's a lot of futex messages in strace output:

futex(0x55b92f416b10, FUTEX_WAKE_PRIVATE, 1) = 1
futex(0x55b92f416470, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, {tv_sec=1619173549, tv_nsec=428281000}, FUTEX_BITSET_MATCH_ANY) = 0

Here's the output of strace -c:

% time     seconds  usecs/call     calls    errors syscall

What can be wrong with it?
