Could not load certificate file: error:02001003:system library:fopen:No such process (0)

Hello, folks.

I have a computer with Windows 10 Enterprise. I want Filezilla to run as the only server service and of course it should be secured via TLS. I have a SSL-Cert and the key to it (Thawte) with matching domain name left. Since port 80 of the domain already runs on another computer with LetsEncrypt, I cannot secure the FTP server with Letsencrypt.

If I enter the key and the CRT at Filzilla I get the message:
"Could not load certificate file: error:02001003:system library:fopen:No such process (0)"

What else do I have to install on my computer to make it work?

Is the certificate in the correct format (PEM)?

It's the typical Form like Apache needs. blah.key and blah.CRT
Text-Files...

-----BEGIN RSA PRIVATE KEY-----
MIIEpQIBAAKCAQEAzUuXJhA4X+/RYYvqMJ8AgEd2Y8xgG+kRd0RTnwboLC9tnGHX
...
G22ynFItG6qiAiyNzf5OQoU2zt57v1UN5/JUjj2F5k7+3hjQm7/2mqc=
-----END RSA PRIVATE KEY-----

and

-----BEGIN CERTIFICATE-----
MIIGNDCCBRygAwIBAgIQD35h8q2pdQE9b4SqLr3C0jANBgkqhkiG9w0BAQsFADBc
...
0itUia6kgL8=
-----END CERTIFICATE-----

If I select a wrong key-format than I can't even close the dialog without Error. So I can close the dialog but get this error in the LOG-Window

Does the Windows account the FileZilla Server service runs under have permissions to access the file?

Its a normal file in c:\certs
So any user should have access ...
