Total Commander 7.02 crash while pressing F5 (copying)

Pressing F5 key should bring up a copying window. Instead it crash-locks the system. No mouse/keyboard reaction. No normal DBG output. KDBG brings the following:

Entered debugger on last-chance exception (Exception Code: 0xc0000005)
(Page Fault)
Memory at 0x00000043 could not be read: Page not present.

This bug is not specific to copying, it may also happen when trying to open a dir in TC. Yet copying is the best way to reproduce it.
