Hey everyone,
so, I tried installing both SQL Server 2019 and SSMS 18, and I got some error during installation. SQL Server 2019 setup went static for about an hour while stopping almost every process and I had to restart (It seems it installed correctly tho, but I only have 1 service related to SQL, SQL Server VSS Writer).
The problem is, when I tried installing SSMS 18, it completely crashed my PC (BSOD something about the kernel), and now I cant even uninstall / repair the program because I get an "Installation error. Can't open installation package, get it touch with the app developer to check if it's a windows installer valid package. ERROR 0x80070654 "
Here's the log and the error:

121972-ssms-setup-esn-20210810093414.log
