I have solved the issue by downloading and running Obsidian in Windows safe mode.
windows button + R ,
“msconfig”,
On the boot tab, checkmark Safe Boot, checkmark Network, press OK,
Restart system,
Start Microsoft Edge, download Obsidian, install Obsidian,
windows button + R ,
“msconfig”,
On the boot tab, uncheckmark Safe Boot, uncheckmark Network, press OK,
Restart.
