Avast Update Helper error 1638

[yoann06]

Hello

Since Avast update on march 23,  I get this error in logs 2 or 3 times each hour

Windows Installer a reconfiguré le produit. Nom du produit : Avast Update Helper. Version du produit : 1.4.136.333. Langue du produit : 1033. Fabricant : AVAST Software. Réussite de la reconfiguration ou état d’erreur : 1638.

PC under WIN 10 Pro 1809 V17763.503
running avast 20.2.2401 (v20.2.5130.561)

i saw other post about same error, but no fix or workaround

it seems maybe linked to a memory leak that crash my PC with a BSOD started nearly same day ... ( Never crashed before )

thanks for help
