Dear all,
as an alternative: you can downgrade to EN 10.50.10 (available through uptodown: Download Evernote 10.50.10 for Windows | Uptodown.com), and the problem disappeared - at least on my machine (Win 10 22H2, 8GB RAM, EN 10.52.8.3911 before down-versioning).
In addition, I opened a support ticket and received the following reply (within 12 hours - nice): 'Upon checking my resources, this issue is a known one and our engineering team is currently working to get this addressed as soon as possible. As a workaround, you may continue using the version 10.50.10, use the Evernote Web on a computer browser, or download and install the old Evernote app for Windows called Evernote Legacy.'
