This bug was fixed in the package intel-microcode - 3.20200609.0ubuntu0.20.04.2
--------------- intel-microcode (3.20200609.0ubuntu0.20.04.2) focal-security; urgency=medium * REGRESSION UPDATE: revert the tmpfiles snippet to do late loading of microcode, this would also happen during package upgrades. Also, in the case of a problematic microcode update, this would prevent booting using an earlier kernel as the late loading would still load the problematic micrcode, forcing the use of the 'dis_ucode_ldr' kernel command line option to recover.
