A family of Microsoft relational database management systems designed for ease of use.
Perhaps this may be a work around until Microsoft release a fix.
Have a Win 10 system backup from Dec 2018 where I found an MSCOMCTL.OCX (version 7.0.52.6282) and replaced the MSCOMCTL.OCX (version 7.0.53.40207) in the directory "C:\Program Files (x86)\Microsoft Office\root\vfs\SystemX86".
After that my Access apps (ver. 1907) with Treeview controls happily jumped to live again.
A note:
In VBA-Tools/references the MSCOMCTL.OCX (version 6.1.98.34) is still "registered" in C:\Wondows\SysWOW64, but it Access doesn't seem to care.
Renamed the MSCOMCTL.OCX file in SysWOW64 but the controls in the Access apps works anyway.
Note 2 - maybe not really important but anyway:
In the Report.wer file in "C:\ProgramData\Microsoft\Windows\WER\ReportArchive" found in Windows logs, Programs after every Access crash, it says the MSCOMCTL.OCX is loaded from "C:\Windows\System32".
Tried copy 32-bit MSCOMCTL.OCX (version 6.1.98.34) to both "C:\Windows\System32" and "C:\Program Files (x86)\Microsoft Office\root\vfs\SystemX86".
Regsvr32 did register the ocx files but it didn't work in Access.
