What is your Windows OS? If Win 10 or Win 11 please include the version and build shown at Settings | System | About | Windows Specifications.
Note that several Windows 11 are reporting error 0xc0000135 with some Windows apps after KB5013943 (OS Build 22000.675) was installed during the May 2022 Patch Tuesday updates of 10-May-2022. See Windows 11: Update KB5013943 Results in Application Error 0xc0000135 in Gunter Born's Tech and Windows World blog for more information. This problem is also being discussed in Susan Bradley's AskWoody.com thread Here Come the May Updates. The Known Issues section of the KB5013943 release notes <here> state that the "After installing this update, some .NET Framework 3.5 apps might have issues or might fail to open" and Gunter Born's blog post (and the KB5013943 release notes) include instructions for re-enabling the .NET Framework 3.5 through the Windows Control Panel or by running DISM commands from a command prompt.
If you don't have a Win 11 OS and/or don't think that your error 0xc0000135 has anything to do with the .NET Framework 3.5 being accidentally disabled during your May 2022 Patch Tuesday updates, please note that Dell is in the process of rolling out a new SupportAssist v184.108.40.206 (I still have SupportAssist v220.127.116.11 on my Inspiron 5584) and multiple people have reported errors when their system tries to install SupportAssist v3.11.x.x - see the threads listed below. Note that hue03's problem was solved by uninstalling the Microsoft .NET Runtime v5.0.16 from Control Panel | Programs | Programs and Features, while crimsom and rgupta1220 still haven't figured out why the buggy SupportAssist v18.104.22.168 installer does not run correctly on their systems.
